I would ask, how much of the cap are you taking off? The whole thing? You only need to shave the top of the cap off, you leave the "shoulders". So it is still rounded with just enough off the top to smoke out of.

If you're looking to lop the whole thing off you might look into a Xikar X8, they come up on Cigarmonster.com for like $15-$20 from time to time. Also they have a lifetime warranty which is good.
