Your choice of gas is your decision, not the group's decision.
If you wanted to use air instead of Nitrox, then you should have done so, no one can tell you otherwise.
Do not let other people dictate your choice of gas or drive profile, that's your responsibility.
And anyone who recommends EAN32 at 130 feet is someone who I would avoid.
I totally agree, what if you were not nitrox certified, was that a condition of the dive. If your an experienced diver (no you personally just generally) you know what works for you and your limitations. If its the dive ops policy for that certain dive well then again a choice the diver needs to make. When I did some wreck diving in NC most dives were in the 120' range and the OP provided 30%, they had a few folks diving air, they just recommended Nitrox.
