GonG Chalice, modeled after the Rastafarian "wisdom pipe." The chalice is similar to a tube, but obviously the diameter is much smaller. The reason for this is so you get the smoke more quickly. I used to strictly puff out of tubes, but I much prefer this now. I can take an equally large draw with a much higher smoke/air ratio. Every time I hit a tube now I'm just waiting for smoke for what feels like an eternity. I'm now trying to knock tubes in any way, just not my thing anymore. I have friends who think the chalice is too harsh, and will much prefer tubes. To each his/her own.
