what do you mean the slide is too big? it looks similar to mine!(its in my glass family thread).

do the slide fit in the bong? and you find the bowl too large? does it have a LARGE(diameter of a cigarette about) hole at the bottom of the bowl, and you cant use because of that? my bongs slide is like that, its kind of a let down that i have to use a screen with a glass bong until i can get a new dif/bowl combo, but in all honesty i really cant taste it.

maybe we can help you rectify your bong problem!
