On my two Rorqual trips this summer the mix was 31% to 32%. Only about 1/3 of the drivers used nitrox on my four Nekton trips. I usually get one hour dives in and it does not matter if I used air or nitrox. Oh, I do like using the 95 cu ft steel tanks! It seems most divers used nitrox for an added safety margin.
