Shrooms, I'd personally stay clear of the PH(x)s. The extra drag the perc chambers produce make it really hard to hit. I personally let anyone use my expensive glass, as long as they can afford to replace it.

POG, you should check out some of the other cats over at tokecity.com. I have what is considered one of the "smaller" collections there (some have over $10,000 worth of glass.. very expensive but a very enjoyable hobby).

Toke on everyone.
