I've got a couple of wasps, for the money they're really good. I think you need a little drip tip because they're prone to spit back. They're also pretty airy, which might suit you. I got the C-Roll from Ambition Mods last week & it's all I've used since. More restrictive, smoother, & better flavour (with my usual build in it) than the wasp. It's not leaked once, zero spit back, nice deck, & no whistling, which the wasp is prone to! Cons are it's only available (from what I've seen) in stainless, & it's a satin finish. The drip tip isnt 510 or 810 so you're stuck with it. Personally I like it. I paid £30 from SR Vapes, you'll probably get it cheaper from China. Well worth considering if you're after a more restricted draw.
