I've been reading and learning and watching the videos. But when it comes time to order, I'm getting confused (in terms of size & ohm's mostly) What will fit and look nice on a eGo Twist/spinner type batteries? I like the size of the mini kanger protank, but the vape is too cool for me. I want/need a warmer vape. Doesn't have to be pyrex since I generally don't use tank cracking liquids. So, halp plz?
