So, I'm thinking now, do I really need 30w? or should I buy some nicer rda/rba's? i can get 15w on my Vamo, but i've just started doing the rebuildable stuff. Will the extra watts make a big difference on flavor and all? ive got a kayfun lite v2 and a smoketech rsbt hybrid, with some drippers otw. and i'm probably going to go to that stuff exclusively.
