I'm not a subtank guy. I build my own coils and such, but I've tried the Arctic and I like it. The Delta 2 is pretty good as well. Not a fan of anything Kanger. Overpriced and sub par. I'm looking at a freemax starre pro though. Those seem to have evrything I like and have a rebuildable head. As far as drippers, decide whether you want flavor or clouds or both, then ask around.
