I have dived with someone using an ordinary cuff dump and the big problem I saw was when doing a valve drill, when they reached for the left post they lost buoyancy as the suit dumped.
That was me - in a rental suit - and it was awful
I couldn't understand why every time I shut my left post I was sinking in the water - but when we surfaced Al explained that the suit had dumped each time I reached back.
Pete - I'm quite convinced that one issue with your suit having seen it is fit, not position of the dump. John Kendall had exacly the same issue with his polar bears suit and resorted to a piece of elastic round the shoulder to stop it ballooning out when air reached the top of the arm.
Having said that, I know you have not had the suit long and wonder whether you also need to take a bit of time to get used to it. Al used to "need" to twist quite violently on ascent to dump his suit but not any more - so it was clearly a technique thing rather than a suit problem. What do you think Al?
