Whenever me and my roomie smoke, we pack it nice and big. Like 5-6 rip's each person, so 10 hits a bowl i guess. I hate people that pack a little ass bowl that's like 1 hitter, i love green spilling over the lip of the bowl packed in tight! Now i know why all the 17 year old kids say "Dude i smoked like 9 bowls and got so messsed up duuuude" I learned a lot of people need 3 bowls worth, because they don't ever pack it tight. Packing it nice and tight, but still some air is great, slow burn with a little oxygen that requires you to really suck in and get it good, without torching it all too much when its being passed
It's all opinion of course, not dogging any smaller bowl packers
