@EverythingsHazy, I don't really think the slant at the bottom of the bubbler mouthpiece is going to work how you're thinking...
Sure it may stop a few ml of water from pooling there after a hit if it bubbled up into the neck, but by the time bubbles are in the neck, the connection between the can and neck won't really matter - you'll get splash back unless yo stop drawing...
Just saying, if I got a bubbler with a connection like that, I'd think it was janky, and seriously consider asking for at least a partial refund.
If I saw that in the pics and knew it was a design element I'd seriously consider skipping the piece...
It may just be me, but if any piece is gonna have a bubbler style mouthpiece, I'd say it should keep the traditional straight / 90 degree exit from the can...
Thoughts?
