I also believe that sliding d-rings are taught by instructors that don't have a high level understanding of the physics of sidemount. I admit, I used them and taught them until I learned from someone much better than myself how to properly setup my cylinders and waist d-rings so that I need one move per cylinder, as they get positive, and my cylinders are always in trim.
Do you have any pics of your tanks full at the beginning of the dive vs empty (~50bar) at the end of the dive?
Interested to see how well the single d ring set up works
