I think what would be an ideal addition for the Sub is an oil catcher that has the "Y adapter" style second chamber off to the side for carb, so you don't have to lift the hot Sub to clear it, but you still have a nice removable chamber to catch the oil in... is it possible PV??
Now thats an awesome idea!
WTG girlfriend, thats using ya noodle!
I was slightly concerned about how sometimes clearing a bong looked a bit clunky(?) in its operation in some vids.
Ease of use is of the upmost concern due to my serious condition.
(I dont have any medical issues, Im just a typical Aussie & I drink alot (a real lot), so on occasions my hand to eye stuff not so good. Plus throw in the odd staggery, waggery & its a recipe for diaster)
and of course one of those knarly little reclaim catcher bottles will make it even more awesome too!
Once again, tops idea Jam.
