ya it's nice i guess, but it does have its downsides, the major one being that I'm a pretty clean cut white kid, and at alot of drug deals with new people i already look like a pretty big narc, but out of common courtesy i usually with spark a joint with a new connection and when i get as blown as i usually do they can get a little shaky. As far as bowl size goes i've been smoking out of my metal bowl vs. my glass. my metal one is about half the size of my glass and my glass's capacity is about a small paper zig zag joint, so i guess it takes less than a bowl to get my blown.
