O2 decompression Real quickly, here's how I do it for my trimix dives (5 regulators: primary bottom, backup bottom, primary nitrox, backup nitrox, oxygen): Bottom mix comes over left shoulder through ODINs, nitrox comes over right shoulder through ScubaPros. Backup bottom mix is on a 5' hose with a yellow plastic second stage, and is attached to the D-ring on my left harness strap with a snorkel-keeper (one loop of the keeper wrapped around itself on the D-ring, the other stretched over the mouthpiece of the regulator). This attachment system allows me to easily yank it off if I need it. Primary bottom mix is on a normal-length hose and has a black plastic 2nd stage (even at 475', it's easy to distinguish black from yellow). I hold it in my hand on the descent (nitrox as travel mix), and clip it off to my waist strap on ascent. Primary nitrox is a ScubaPro G250 (round plastic) 2nd-stage and is attaced to the D-ring on my right harness strap with a snorkel-keeper. Backup nitrox is a ScubaPro D-350 (palstic triangularish) 2nd stage and is clipped to my waist strap with a brass clip. O2 is an old Scubapro Mk-V (metal round...present "Balanced Adjustable" 2nd stage is similar and better) that is attached to the back-mounted O2 pony bottle with elastic bands to there is no way to accidently grab it in a stressful situation at depth. If I wanted tactile differences between the primary and backup bottom mix regulators, I'd probably put a few large cable ties around the primary second stage.
