yepper, I've even went with 3.5mm but thats when it starts getting tight (but works)
I clip it off very close also, I don't even worry about ANY sticking out, just as long as it plugs the hole...
the inside of the air tube (bell inside the tank) is where you can get flow restriction
if you cram TOO MUCH wick into that 'bell' it doesn't allow as much absorbtion, as one would like - IMO
I've tried to switch over to short fat, from long skinny for wicking configuration...
