I bet I have built close to 100 builds on the SubTank Mini RDA.  I can tell you from experience that te best wicking possible you want it so tight you think it is going to screw up your coil.  In fact sometimes it does and I have to do a lot of adjusting after it is wicked.  Another tip is to trim your tails so that they just barely touch the deck.  You want them to fan out but not to cover the holes.
 
Here is a picture I took from one of the other forums (not my picture).
 
 

  The general concensus over there is the best coil size is in the 2.5mm range and to stuff as much as 6mm wide of Japenese cotton only removing one of the covering layers from one side.   I have gone back to using rayon and may post a picture tonight if I get a chance to rebuild.   By the way, I run 1.5 ohms and 70pg/30vg juice @ 20 watts on the middle air holes.  I do not take extremely long draws, but not short either.

LOL!

I don't know. I think this is pointless. The board is huge! I have been trying to draw up a box that I could have 3d printed, and it isn't turning out any smaller (with dual 18650s). Possibly more ergonomic though...lol

I have had great luck with these guys http://www.varitube.com/ They don't have DNA stuff, but they do have quite a bit of DIY parts. I have personally had better luck with their 510 connectors than I have Fat Daddy's. This is just my opinion, many others have had the opposite!

it is the only language I know.  If I can just keep one vapor from ending up on the news with a injury, by boring them to death with geek speak...I have succeeded.

to me!!!
Today marks 2 years since I purchased my first vape kit and gave up the analogs.  It was a belated birthday gift to myself that I have come to view as a "re-birth day".
Don't normally like to toot my own horn or pat myself on the back, but today truly is a milestone for me.
 

To celebrate my 3 year vape-versary (Feb. 8th) I bought myself  an Innokin Coolfire IV TC 75W mod, a new Limitless Plus RTA, and some assorted vaping  "stuff".   I'm not a high-wattage vaper so I'm hoping to get the same good experience with the Coolfire IV I've gotten with my EVic mini. 40-50W suits me fine, at least right now. That may change, maybe not. Who knows. Hmm, may need more batteries...............
If anyone had told me  3+ years ago that vaping would get me off the stinkies for good, I'd have probably reacted with "yeah right". Thank goodness for the co-worker that talked me into trying vaping. I've felt physically better than I have in years, my allergy medications have been cut in half, now just to get the extra weight off.  >>sigh<< Despite all the money I've spent on vaping gear, I know I have still SAVED money not buying stinkies.
 

@Adversarious1  Ok, bonded with the GX350 in a day flat. Obviously I can't speak to reliability over time but here is what I got:
First thing I noticed on removing the mod from the box is that without batteries the battery door does not want to stay shut.  No latching without batteries.  Battery door is well marked for battery orientation and the batteries that I used fit nicely in the sleeves provided.  It takes a fair amount of pressure to close the battery door with batteries installed.  The battery door bows slightly with batteries installed.  Sitting on a flat surface the mod will rock slightly from front to back.  It sits flat from side to side.  The mod is not easily knocked over.   Griping the mod is absolutely perfect for me.  I have fairly large hands.  The shape of the mod fits the natural hand grip the best of any mod I've used to date.  Very substantial feeling mod with no rattles.  The firing bar is extremely stable with no movement beyond it's intended travel for firing.  It is not extremely "clicky" but has a subtle but noticeable firing point.  There is a very short delay in firing.  Seems instantaneous to me.    Obviously the mod has some weight to it per four 18650 batteries.  I have carried it in a fleece jacket pocket but it is a lot of bulk for most pockets.  I really enjoy the top mounted screen.  I like looking at the screen after most every vape (no idea why) and it is very handy.  It also came in handy testing TC.  Too close to focus on while vaping but I could tell when it was going in and out of firing.  A friend who works at a vape shop mentioned that other top screen mods have had failures on top mounted screens due to juice getting into the display.  Time will tell.  The screen is raised.  I have up to 25mm tanks and they fit well.  A 25mm is close to max without hitting the screen.  The center pin on the 510 is stiff.  I have one tank that will not screw flush with the mod.  Zero problems with connectivity to tanks/RTA's/eieio.  The screen itself displays all necessary information including a puff time which latches between puffs.  There is a puff counter but to view it you must enter the menu system.  The puff counter also latches and must be reset via the menu.  The mod is designed to detect atomizer changes and query input, new or old tank.  I find this somewhat accurate.  I like to fire the device once without a tank between changes to ensure the new atomizer is recognized.  In TC the unit appears to be using the initial atomizer resistance as a base line as there is no facility for locking resistance.  Temp control is simple.  NI, TI, and SS.  The menu prompts you for available wattage and TCR value.  I am using a value of 88 for 316L and am getting a very smooth, very well regulated vape without obvious on and off periods.  In TC the temp itself is the primary display and is adjustable via up/down buttons on the mod.  There is no ramp adjustment in TC.  Both TC and VW modes latch.  Most menu adjustments can be achieved with only the fire button using either short or long presses.  Values have to be changed via the up/down buttons on the mod.  The up/down switches are under a rocker style button which can be pressed in center to lock the mod.  I have found no facility to lock settings while allowing the mod to fire.  Pressing the fire bar along with up or down button will take you to short cuts for changing wattage and mode in TC.  In VW mode the short cuts are ramp strength and mode.  The mod powers up with five clicks and powers down via menu.  I am estimating battery life to be between 700 and 750 vapes.  Low wattage vapes ( 30 - 50) @ approx 6-7 seconds, high wattage vapes (90 - 110) at 2-3 seconds.  The USB port has a rubber cover.  IMHO, nice touch.  Paint; Smok and paint; I already have three small chips in the paint.  Although tiny and on sharp edges, I am assuming it isn't the best paint job on the planet. 
 
Opinion:  I love using this mod.  Fits like a glove and all functions work well and are easily accessed.  I actually like the weight.  Feels substantial.  Sits well at the desk or end table.  Rides nicely in the console of the car.  It's small enough for me to palm shift while driving and holding the mod.  I think my other mods are going to get lonely. 

Got my Mutation X v5 from the VT store.  I was excited and neglected to take pics before breaking it out and building on it.  Ridiculously easy to build on.  Basic dual coil build.  22ga 316L SS at .15Ω.  Already wicked.  Sitting on one of my Sigelei Fuchai 213's.  Vaping @570 degrees.  Airflow for DAYS!!  Love it!

I don't steep.  I make my flavor base 120 ml at a time.  I then mix up 100 ml of finished juice.  I guess it does steep, or at least age, because it is normally a week, or longer before I vape the 2 50 ml bottles that i mixed up and 120 ml of the concentrate lasts quite a while.  I normally have 2 50 ml bottles.  I keep 1 in the console of the pickup, along with 4 fresh batteries, and an extra NEBOX, and a couple of rebuilt RDAs.  I keep the same thing in my laptop bag.  I have been on the road 4 days and 3 nights with this new territory.  I take double backups just in case my pickup, or laptop bag and I get separated.  Of course if something happens to my truck and the laptop bag is in it I'm screwed.

Yeah, it was kind of a bad deal.  The one I ordered was really slick, when they never actually produced it, I was really bummed.  I ended up getting the in store credit, and buying a brother to the one they never made, and it turned out to have one of the worst chipsets I have ever had.  It is now sitting in my "I don't use these any more, shelf".  I am getting pretty much like @bcartervol98  I have my mod/tank I really like for every day vaping, so I bought 15 of them.  Shinyitus, has worn off, so it has to be a heck of a deal before I will jump out there and get something new.  Since my last experience with preorders was so bad, I won't do it again.

I use the same Nic base and really like it.  I have about 2.5 liters left.  I actually keep mine in the original bottles.  I pull out about 50 ml at a time as needed.  I also store the bottles vertically inside a heavy zip lock bag.  I found out the hard way, that they leak if you just throw them in the freezer on their side. Luckily it was in a zip lock.

Enjoy!
I have really enjoyed making my own juice.  I don't make many flavors, but my main flavor has 23 different fruits, and creams in it.  I do change it up a bit by adding a bit more or less of some flavors to emphasize other flavors.
I don't ever worry if I have enough juice on hand, I can just go mix some up when I need it.  I also make flavor concentrates out of my flavors.  Basically I just add all of the flavors in the proper amounts so that it equals 120ml of pure flavors.  So I just have to add VG and Nic base.  It takes like 3 minutes to make up 100 ml.

@Tam @Edna  Ya Edna, that's right.  It's all Tam's fault.  I even told my wife that.  Tam made me do it!  Backups!!!!!!   Ok, so we've been eating ham sandwiches for a month.  What's wrong with that?  Ham and bread are healthy!  Just like vaping!  I don't see a problem here.  

The first step to the creation of Wally's laboratory is complete.  510ml of PG, VG, Nic base is in, along with a butt load of small bottles.  Now I just have to decide a a few recopies to try and order some flavors.  This is the hard part.   

Walmart $14.97 in the craft section I added ceramic tweezers and the stuff that you line a drawer with it helps my mod not move when I am building.

I did add a mini fridge to my office/vape room to store some of my DIY vape supplies.
Actually since I semi-retired my office has become more of a vape hobby room.

I actually had the optivisor because I build scale models (cars, tanks, planes, etc.)  Some of the parts I work with are very small, so those help.  I merely took a tool in my box that was intended for one thing and adapted it for another.  Sort of like what you're doing.
 

I learned order juice well before you need it. 
I normally order when I get to 60 - 80 ml of my ADV.  I thought I had 2 30's and about 20 left in my big bottle.  I didn't.  Comp has been rushing around to fix my mistake, but it isn't looking good!  My juice should be here on Friday.  I have drained all of my tanks (I know, not good).  I have cut it with VG/PG and added a little more nic....
It looks like I have to go to the B&M tomorrow....  I would rather get a root canal....

Lower resistance = more heat, and Nicotine is absorbed faster (and felt more) by the body as heat increases, which is why you get a stronger Nicotine "buzz" and more throat-hit from Nicotine if you lower your resistance of your coil (but don't lower the % of Nicotine by the same amount).
@Tam's example is spot-on... she dropped her coil resistance by 75% (roughly), and needed to drop her Nicotine by the same 75% (12mg to 3mg) to get the same "feeling", and the same Nicotine absorption.
Nicotine absorption rate is a little complicated (math), but the basic rule-of-thumb for vaping is, if you lower (or raise) your coil resistance by X%, then you should lower (or raise) your Nicotine level by the same X%, to maintain your absorption and Nicotine feel/effect.  The relationship is nearly linear above 0.5 Ohms, with a steeper curve below 0.5 Ohms because power and heat increase more as you approach zero resistance.... This is why Temperature Control devices have become more popular for those who sub-ohm 0.5 Ohm coils and lower   TC devices allow you to control the temperature / heat, so you can (for the most part) use the same juice with a 0.5 Ohm coil as you do with a 0.2 Ohm coil, but you'd still find a lower Nicotine level more appropriate (even when using TC-mode) with a lower Ohm coil, than you would with, say, a 1.2, 1.5, or 1.8 Ohm coil.

I like it!  I am definitely in the "Crank it up" camp

What's interesting to me is that we know what factors contribute to a successful coil.  As Rich has mentioned the key points - Airflow, coil position, and wicking.  But that it seems to differ between tanks is a bit of a mystery to me.  All coils operate on the same basic principles. But it seems funny that the tiny difference in airflow between tanks, or the length of a chimney, or that the coil sits a tiny bit further from the air source in one tank or another vs the other makes enough difference to be able to perceive that difference is kind of amazing.  

In my opinion which isn't right most of the time, it has to do with coil, and airflow, airflow across the coil is very important. The tank itself is just something to hold the juice, of course chimney length probably is a factor too.
Whether the coil is horizontal or vertical could be a factor too.
Wicking could be a factor too, personally I think Rayon gives a better flavor than cotton, but that's just my opinion too. 

Yes, yes you are. What are you going to do to rectify this?
