I've tried some MTL kits and didn't find the vape very satisfying. I started to close of the air on my DTL tanks and found that I really enjoyed restricted lung hits. They use less juice and don't cloud up the room. This will become increasingly important for indoor vaping as temps drop. I purchased my first true MTL tank a month or so back, a Dvarw MTL RTA and learnt how to make my own coils. I'm really enjoying it but wonder what else I should try. I was also recommended a Kayfun Prime RTA. I didn't get one before because I was reading that it is more of a PITA to fill than the Dvawr. I have since realised that the Prime is a top fill design. What other tanks should I be looking at? Easy to build, easy to fill MTL to DTL restricted lung hit?
