You can't beat a green hit from a clean bong with fresh water. That's just how weed should taste. That being said, water never gets changed enough and I don't know that I've ever cleaned any of my glass, aside from scraping the bowls when I was fiending. You can control how much you smoke in a bong based on how many bowls you pack, and how big you pack them. With a blunt you are almost forced to smoke a gram at a time. Thats just not practical when you smoke alone more than 2 times a day (at least for me). I love blunts, but usually only smoke them in groups, or other "special occassions."
