don't get me wrong. i am a fan of no external air lines. i try to buy all markers designed like that. i think it was a great idea. i just wanted to make sure they though of ofther set ups. i don't think it would be hard at all. just need a way to seal the line not being used.
Janek, any chance of getting differnt detents in the future? the wire ones are not bad, but a dual system would maybe help some.
