I'd go with the Nautilus mini with its vertical coil at around 1.8 ohms. Then, the juice ratio would come into it. Like I said, you don't want to go higher than a 30/70 (the first number is PG and the second is VG). I vape a 50/50 and have to use a fan sometimes to air out the room. YMMV. The way you hit it will also make a difference. Vaping is different from smoking. Try taking long, slow drags at least 4 - 7 seconds and see if that helps.
With more air flow I think you can get a bigger pull and a smoother drag at the same time.
Others should be along shortly to give you their two cents and suggestions. Nearly everything with vaping is subjective. What works and tastes great for one will be awful for another. Only you will be able to figure out what works for you.
Try the links (underlined key words) in each post. They'll take you to the Vapor Talk store. Best prices I've found online of the things I use, and I'm not saying that just because I'm an admin on this forum.
