| I don't know if anyone else finds this, but I tend to notice diving air versus 32% after a weekend of even shallow diving, if I've been on air I feel tired but if I've been diving nitrox I tend to feel noticeably less tired. Random lots-of-helium mix I ended up with in some twins the other day seemed to have a similar effect. Whether this means I'm normally decompressing really badly on air I'm not sure...
Regardless, I appear to be scheduled to do one of these new nitrox workshop thingys with some ocean diver trainees in a few weeks and wait with interest to see how it goes!
