OP, thank you for sharing. I appreciate the conversation and your candor.
As a slight digression, I purposefully went overweighted this weekend so that I could get my "heavy breather" son to try out less weight. (We didn't have a good combination of one, two or three pounders for all four of us. I made him take my six pounds and I took his ten.) It was fairly drastic how much more I had to futz with my BC to get neutral, and how much that could change with depth. I also used more air as I worked to swim up or down. His gas consumption was noticeably better and my comfort level was noticeably not. LDS will be visited promptly for more weights in the small range.
This has been a godsend for me as I have worked at my buoyancy, trim and weighting. Go a little bit head down and pull. Seems to be the only way to get even close to zero air in the BC.I exclusively use my butt dump.
