The specific mix requirements all harken back to the original purpose of the dive. If the shipwreck is at 150 is still water on a sandy bottom, with no currents, air isnt too bad for an external survey dive like that.
If it looks like it will become more complicated, then 20% helium & 80% air works well for 150 fsw. If you insist!
You will miss The Sea Ranch if you dont go, seahunt(small-s)!
