personally, I tend to go with the newest and shiniest (I'm waiting for some 3.5ml dual coils to come in as we speak), so that may not make me a good judge of what would work
I've been on a clear kick lately, I like to see what my juice is up to, so CE2s, things like that (not a fan of the G4s, they need more work). The kids these days all seem to like those dual coils as well.
