yeah, a surefire way to get a bellringer is to get your chore niiice and greased up with resin. sucking back slowly but surely on the pipe will allow you to fill your lungs with a LOT more smoke, too - once your chore is sticky enough it's impossible to hoot all the resin at once.
be damn careful not to heat the chore up too much though. i was using a metal pipe and it got red hot and shot to the back of the pipe, and fi it wasn't for a little rubber tube i had on the end it would've been lodged in my throat instead of in that thing.
