Ehle 250ml with some attachments would be good. could get active carbon, diffuser nice bowl something like that.
bubble/beaker bottom bongs = shit ton of smoke thick glass glass on glass defused big but not too big (stashable yet still badass) ice notches transparent!!!!! just my basic little check list i follow wen i go shopping i also live in socal. if you live in or near moorpark/thousand oaks/simi valley a great smoke shop is "dough main." cool workers and great merchandise hoped this helped!
pretty much somes it up definately go for the thicker glass, stable base, glass on glass, and whatever design floats your boat
