When I got away from the jacket BC and started up with a shop that I did my tech training through, and subsequent instructor path, I made a decision. That was to become as familiar as possible with as many different OC configurations/styles as possible.
Jackets, back inflates, BPW's, long hose, standard rec hose set up, variations on that, etc. It didn't take long to come to the realization, as Ray has pointed out, that they are essentially all the same. Once I did that I started mixing them up further by using gear that was too small, too big, and just right. Again it turned out that it really didn't make a difference. Even when I intentionally over weighted myself I could still, and still can, get into trim and stay neutral. But it's so much easier to not overweight.
As an instructor I chose to teach a system that required a much more significant amount of time in the pool than I got in my own OW class. I started using that time to show and put students in jackets, back inflates, BPW's, long hoses, and standard rec set ups. Since I also explain the similarities and the MINOR differences I have yet to have a student be confused, frustrated, or experience and other negative effects.
I do think it's a shame that there are OW divers out there from many informed and skilled instructors that seem to know more than CD's and IT's when it comes to reality and gear.

The 90 degree is a fixed adapter as is the 70 degree that others like myself use. Each end will rotate 360 degrees in one plane. A swivel is omni-directional and rotates around the center between the ends.

Thanks. Is the 90* swivel a fixed L shaped adapter? Can the adapter be straightened?
