Whats up grasscity, I'm lookin for a bong and was wondering about the disadvantages of the thinner roor bongs. I really don't want to spend over 200 dollars for a bong, but still value quality. So does anyone have any experience with the thinner roor models or have any words of wisdom? I was also looking at the mad scientist and would probably get the pre cooler with it. Some of the roor models im interested in are the roor 3.2 35 cm and the roor custom bong 3.2 mini master. If there are any roor models under 200 dollars that are under 200 please let me know, any other feedback is appreciated.
