Just pack individuals. Its been a while since i've just packed a bong and passed it around. Anyone who understands how a vaporizor works, knows why individual packings are the best.

Think about it. A flame is roughly 800 degrees and thc vaporizes at around 350. After one hit 85% of the thc is out of the bowl.

Even though the corner method is a bit better then the norm. Individuals are really the way to go. Once you switch methods you'll never go back i promise you.
