...I've heard in certain circles that if you put an "Auto" dump on a compressed neoprene suit it doesn't vent properly and can cause a rapid ascent. The reason given is that the suit expands and takes the pressure of the the spring in the auto dump, and therefore you have to have a "Cuff" dump fitted...
You need to stay out of those circles lest you hear more stuff like this.
