dude, i had a regular sized resinator pipe, and i put an 1/8th in it, and smoked another 1/8th thru it in one nite, and the next morning, i took one hit off the shit from my chamber and was fried.

P.S. the plastic resinaters melt if u smoke to many bowls, althu if u smoke that many bowls to melt a plastic one, then if u smoked the same amount in one secion, u r gonna have a hot pipe, so i would go with the metal and wrap it in sum black tape
