LG Diver:This is good to hear. I have a 22" hose on mine at the moment and can't rotate my head to the left all the way. I thought I was doing something wrong. I didn't want to just go buy a longer hose until I played with hose routing a little more, but it sounds like others are going with the 24" on a single-tank config also.
serrada:For the primary most people seem to use the 7' hose. On a single tank what hose lenght are you guys using going to your backup. I think a hose too long might be uncomfortable.
Vie:It depends on your first stage.
