Okay, so I've only ever had two pieces a mini bowl and a regular clear bowl my sister gave me awhile back (Don' get me wrong, the bowls are GOOD). I just ordered an acrylic bong and a ROOR steamroller. Are those good things to move up to or should I have chosen something else? And I see a lot of pipes that look a hell of a lot like bowls. Are they the same or do they not have a shotgun? (Sorry, I'm not good with all the pieces)
Honestly I have been through the phase of loving a steam roller but moved on quickly. The water diffusion in a bong is highly advantageous in smoothness than a hit from a steamroller. I think the acrylic bong was a bad idea. The RooR steamrollers are pretty cool, and you will have fun with it for a while. If you need advice as to what piece to get next, PM me.
