I bought this and my girlfriend bought me the Phoenix ashcatcher and the helix premix chamber for my birthday. I love the setup. The honeycomb perc is sooooo smooth. Hits feel like a dream. I couldn't be more happy with this purchase! Definitely go with the 16"
Wonderful pipe. Smooth easy pulls, nice stacking, and well built. Grav makes excellent pipes - now have 8 waterpipes made by Grav - all beautiful, functional, and well made.
