yeah were forgetting bowl size too. Example, both my glass bongs hold upwards of a gram each bowl, which is PRETTY hard to snap. However my 18" plastic by comparison, has a little tiny metal cone bowl(oyu know the ones) that hodls like a .2. So, while ill take that sucker down in one hit without second thought, and leave the next person to pack a new one, on my other bongs sometimes its jsut more convenioent to pack a MASSIVE bowl, and pass it around working from the corner or the bowl untill its cashed. If we aint high enough, then i guess we need to pack another biggie!
