I've got a hands free vapor brothers and my only complaint is that it is a pain in the ass to change the screen. Sometimes I pop that thing in there in seconds, other times I struggle with it for what seems like forever. Noticed Vapor Brothers came out with an easy change whip kit with ceramic screens. Anybody have an experience with this whip? Not sure if I can justify spending $60 just so I can stop bitching about changing screens.... Also, where does everybody get there clear tubing? They recommend only using "medical grade" tubing. So if anyone knows where I can pick up 20' or so, I'd really appreciate it!
