I've never personally used one of those, but I've HAD a Water Bong before which was cool, and normally I keep a bowl at the house as I can use that whenever and don't have to show off my terrible fuckin' rolling skills (The Wife rolls wonderful joints AND blunts, so I don't HAVE to do it,and therefore suck at it) and I've used other designs of pipes before too, but my current bowl is a Silicone one that the Wife got me I think as a Birthday gift; the bowl part is glass, and the rest is Silicone and I like that.
I like Joints and Blunts the most though; Easier to have one ready to go if I want, and normally I grind up a bunch of weed, and then hand my tray over so it can be rolled up. I've had more guppies in my mouth than some Piranhas I'm sure LOL.
Amos you have your own papers? That's awesome!
I do want to try this contraption I saw in a video on YouTube of a dude that was travelling in Afghanistan and was in this little lace that people smoked Hash in, and it was huge and they would power hit that and cough and..... LOL it looked cool and looked like you could put quite the load of Hash in there haha.
