What's the best coil builds for cloud chasing on a twisted messes and mutilator rda with a nemesis mod?

Heat in the center of the tube could be the battery, and could also be dirty threads... dirt and corrosion add resistance. 
Take it apart, clean it well, inside and out... clean the threads with a stiff brush (toothbrush, wire-brush, etc.), and use a good metal polish/cleaner on the entire MOD.  Lubricate the threads with a low-resistance anti-seize compound... or use a tiny bit of Vaseline if you have nothing else for the threads.
If it still heats up after that, the battery is the most likely cause.  Either get a better battery, or build your coils to a higher resistance so the Amp draw is less!

O.22Ohms @ 4.1V is 18.6A... @ 4.2V is 19.1A...   (and this is assuming zero-loss of power across the MOD, which is not possible, so add a couple Amps to the overhead).
The VTC5 is only rated to 20A continuous discharge (<100C), and most tests I've seen rate them lower than this.  For proven 20A performance, I'd look at the Samsung 25R or the VTC4.  Both are proven to perform consistently at 20A, with a margin of safety for higher loads... and the Samsung can usually be found for about half the price of the Sony, even on the Liion site!
If you're not exceeding 20A with your coil, then your Nemesis Fire-button spring is likely the culprit (heating up like a coil as you make contact).  I would suggest upgrading to magnetic fire-button connection, or at the very least, upgrading to a heavier spring.  Also, be sure to clean ALL the threading and the components of the fire-button.  Dirt can also create a situation where heat is generated.

+1 to what earth said. 
VTC4s are great! It does have lower capacity compared to 25R and LG HG2, and twice the price point (sometimes more) of 25R. Others who are not pushing very high wattage find 25R, etc are good enough for their needs. 
If power requirements is more important than longer battery run and do not mind the price, authentic VTC4s  all the way.  

Hey everyone! I'm New here and wanted to introduce myself! Have a good day people's!

No one needs a super high powered mod, but if you truly want one, we just want to make sure you know what you're doing with battery safety so you don't get hurt. It's a lot like no one really needs a Lamborghini, but if you really wanted one and had the money for it, we would suggest special driving courses to keep you safe.
