Meh, to each is own, I use a carb bong because thats all I have, but I have used slide bongs as well. I really don't prefer one over the other, and I can deal with each. But with a carb I make little whirlwinds when I draw, and when I let go of the carb I take a fat ass draw to clear the smoke and bring in new smoke, and let go of the carb. REPEAT AS NEEDED lol but with a slide its alot easier, and no fucking laps of water to worry about either.
