I plugged mine up permanently. I have carbs on my bowl, but one of the things I love about a bong is that I can slide it to clear, so I'm gunna. If I wanna use a carb, I'll use my bowl. It's all up to personal preference. And it depends on your financial situation. Look around the grasscity shop for a while.
go with a nice glass on glass my fellow mn toker you can get a nice stright tube gong for around 80-100
It's very strange. In Europe most bongs sold there do have carbs on them. You don't see many in the US anymore. It's mainly because carbs on bongs are retarded when they're glass on glass and have a slide anyway. The fuck am I going to use a carb for? So yeah, no carb.
