Bro, out of a four footer...that's why they call them "Suiciders" I would recommend toning the size of your bong down, I have an 18 in. and thats seriously all that I can handle. I've hit a five footer before and to tell you the truth I really don't like them, it is too much air to suck through so you have to clear in a couple of breaths and the smoke in the chamber gets stale and rank. My advice is go with a smaller bong
