I'm almost always smoking with one other person, sometimes its a group of 3, and I rarely smoke in large groups anymore. When I'm with just one other guy (who typically also has a very high tolerance) we usually weigh out .35 to .45 of top grade and divide that into two bowl packs. We take huge tokes so it usually only takes a short while to smoke.

A lot of people claim to need to smoke more in one sitting then that (it comes out to roughly .2 each) but I inhale very very deeply and take very large rips.

With my bong atleast, it milks very fast and I pull hard for a good while completely milked and then I carb the bong really fast and hold it in a good while.

As far as lighting it goes, the buds always grinded very well and and I light the whole bowl for about a second until the whole bowl starts to cherry itself as one.
