Ok, so I'm going to ask...I know there's at least one die-hard fan here (duh!) but I've got some questions about them. What are their benefits? What are their drawbacks? Why do people like them? Not trying to be rude, but I find them rather unappealing from a visual perspective (but to each their own). Yet, I understand that smoking is (to me) more about pleasure than looking "cool." Oh, yeah, and what about cleaning those funky looking stems? Any feedback is appreciated...I'm just trying to get my head around these things!
