Why? I'm not a CCR diver, but I have noticed several decent/good divers go from diving flat on OC to a knee down trim on CC, and it's rare to see a CCR diver with "good trim". Why is that? I would think that having good trim would be just as important, if not more, on CC with increased drag etc. Also as one of the ways you make small depth adjustments is simply swimming up/down since you can't use the lungs. And if the trim even affects the ability to use fundamental techniques such as backfinning, what's the justification for the knee-down trim? Is it just that much harder to trim out that people give up? Are there any reasons why knee down trim would be advantageous? It's a genuine question, since I don't know...maybe except backfinning, I find that sometimes tricky on a CCR due to different trim.

By sidemount you mean widemount CCRs like Kiss or Gemini? Because true sidemounts like Liberty or FX CCRs are actually really sensitive to trim.Not an issue with chest mount or sidemount CCR units.

Always dive with dil and bailout side mounted.With chest mount you probably don’t want to be super flat either if diving with back mounted dil.
