I like to dive on Nitrox just as an added safety factor , my advanced age and all. I'm all of 51 years old.
I was told by a kid at a dive shop that I should dive nitrox because I'm old. Its kinda funny because, I was walking thru the door with 2 steel 100's in hand, and gave them off to him to fill. He had a tough time lifting both tanks and moving them to the fill station. I may be old in his eyes, but I'm not that old.
I am now mixing my own nitrox, just so I don't need to hear how old I am.
I see the benifit in diving nitrox in that my NDL time is much better on nitrox. My normal dive buddy Dale and I can now do a couple of 90 minute dives at the local quarry without any problems.
