I'm thinking about getting myself a new ashcatcher for my inline bong. I would love the extra diffusion, making my rips a bit cooler. My buddy has a 6 arm tree perc bong and I love it. So I was looking in to getting a tree perc ash catcher. (Just from a local shop). I was wondering what kind of A/C's do you guys use and why? Also, is there any reason that tree A/C's arn't very good, because I really don't see alot of them, mostly just Inline, Circs, and showerheads. Thanks guys.
