I currently own a medicali and a small 100ml roor straight tube. I had a question come across my mind that seemed legitimate so here is is, Are attachments such as ash cashers even really worth it for such a small bong?
I like ash catchers since they keep my bong clean so yes. But some of them will add to much drag, and could make your piece unbalanced and more likely to tip.
YES, a nice one is like having a whole separate bubbler attached to help cool the smoke. a small bong shouldnt have issues with drag so buy one son!
Make sure you try to get a smaller ash catcher because it can make your bong easy to knock over, especially with your Roor. And something always seems to break in these situations - either you down stem, bong joint, and or ash catcher joint will break. O maybe all of the above.
