Your post makes no sense to me at all. When a discussion tread is listed as "The Equipment of Scuba Diving/Buoyancy Compensators (BC's) and Weight Systems", I think it's the perfect place to ask a question about a BC and users experience with it. I guess I'll go elsewhere for answers...
You're in the right place, a BC is a BC, no matter if it's a jacket, BI, or BP/W....they ALL do the same thing---ie allow air in & out of a bag on your back....
