thats a good point nochowder, an oversized bong can actually be LESS efficient if youre milking it every time fully, and need to finish it in two hits. Theres goign to be a bit of escapage, adn the smoke gets alittle stale. although my method on ANY bong, is milk as much as i can take in a hit. and recetnly ive been doing lots of snappers, 0 wasted smoke!

what pisses ME off, is when peoepl milk your bong, really thick and completely, by torching the bowl the entire time they hit, and THEN as soon as the smoke hits their lips practically, they go into a fit of coughing and complaining. god the kids at my school are lame.
