It seems perhaps that is the case. I look forward to trying out having less air in my wing on the surface. Perhaps even the dry suit isn't purged of all ( or at least as much as possible) air. I do break the neck seal and try to get all the air out after donning the suit.I just straighten my legs, stop kicking, and let gravity rotate me head up. Alternatively, with one leg (or 2 if you need) pointed vertically down for leverage and hinged at the waist, just contract the glutes & lower back muscles to straighten. I wonder if you have excessive air in the wing?
Thank you for your input!
