I have both...first the bottom feeder is not an airy draw, its a lighter draw meaning you don't have to suck as hard to get lots of vapor...make sure
you prime it well with juice before using and keep it wet...
the regular hybrid is a tighter draw than the bottomfeeder but you still don't have to suck as hard as on a standard atty..
if you think in terms of the bottomfeeder being like drinking water through a straw and a standard atty like drinking a milkshake through one
with the regular hybrid in the middle...that being said both hybrids work flawlessly...the hybrid bottom feeder is the best atty I've ever used..
great vapor and awesome flavor...
