Hello all, just about to make my first bong purchase...ever, once the ALT's sale goes live! Just curious, what if I plan on combusting (very occasionally), burning oil, and vaping in the same piece? Does combusting in the glass pretty much ruin it and very hard to clean? What about if I got an ashcatcher? What about concentrates? I seen a few people using theirs and it looks pretty nasty with oil all over the place, is that easily cleaned? Should I really own three different pieces for these three different smoking methods? Thanks for any help everyone!
