This thread could not have explained my situation any more closely (although i am a little shorter). I just bought the setup shown (from leisure pro also), as I am am also a real fat guy. I have had a sherwood avis BCD for about two years now and while I was happy with everything, it never really felt that comfortable, it would shift and tend to move up under water. I checked this out thoroughly before placing the order and there are cheaper options, but once I added everything up, the difference was not all that much and the convenience of knowing everything is together made my decision for me. Whatever you go for, it is my understanding, for guys are size, its very important to get the stainless steel plate vs the lighter aluminum or travel plate as it adds about 3kg of weight. Now I am trying to figure out how much weight I need to add on the weight belt. I currently weight about 265lbs, 5'8", i typically never dive with a wetsuit (most of my diving is in southeast asia). With the jacket bcd, I used to use 7kg (but I was about 20lbs heavier), but from what i have read switching to a bp/w, will instantly save a kg or two as its far less buoyant (less material), the backplate should save about 3kg, the single tank adapter another 1kg. Im thinking of starting out with an extra 3kg around my waste (thinking it will be on the heavy side) and see how it goes, any recommendations?
