i think cornering a bowl is just common courtesy with my friends. usually when its just me and my buddy and his girl we pack either ground up bud or just by the nug. usually though we grind up a nice pile of herb and then load singles but it seems like most people just torch grinded bowls. but with nugs people dont seem to torch as much.

so i guess what im saying is yes we all corner the bowl rather its grinded or a nug. then again with the beginers i think nugs are better because they dont seem to torch as much, while grinded bowls with someone that cant control how big there hit is will get too much because ground up stuff will burn like wildfire.
