I don't mean to sound elitest but it really scares me when I hear divers 
saying "righty tighty left loosey". I firmly believe that if you are 
going to do serious diving the direction of opening and closing a vale 
should be rather automatic. The last time I dived with a new cave buddy 
he asked me if I could turn ON his air. My reply was if you can't turn it 
on then how are you going to turn it off in a free flow situtaion? AND 
that last 1/3 is MY AIR.
I helped him adjust his harness so that he could reach his valves and all 
went well. I have no problem turning my valves, but I have never tried it 
with mitts or three fingered gloves.
