I'm a new diver--received my C-card this past June--and am looking to buy my first BC. I had the chance to try a few BCs and rear inflation seems the most comfortable. I've read a lot about the Cressi Sub Back Jac. It sounds great and the price is right, but I haven't been able to find any reviews. Does anyone have an opinion on this BC, or a suggestion on what I might consider other than the Back Jac? Thanks in advance.
