I thought I would add that I recently purchased Scubapros latest Stablizer (stab) jacket the "Classic unlimited". I had misgivings about this at first because I am not a big fan of integrated weights, at least not when more than 8-10lbs is needed. Anyway, since they no longer offer the "sport" non-integrated version I purchased their top of the line Stab. I was concerned that it would be bulky due to the weight pockets, ruining the streamlined fit. I am happy to say that I was wrong to this regard. The jacket is still stream lined, the weight pockets are easily dispensed with leaving additional pockets for your SPG etc... D-rings are strong & plenty, build quality is higher than any other BC I have donned to date. The material seems bullet proof, albeit a bit stiff but so strong! Lift is very high in the large version at around 60lbs and performs like the older version. it's stability in any diving position is great. It is a bit heavy at 10lbs, removing the weigh pockets takes this down a bit and the cummerbund can also be removed if desired. All in all i am very happy with this BC but still wish they would re-release a non-integrated version. This version however is heavier duty than the sport (double coated neoprene bladder), has a few nice comfort features, can be used non-integrated and is designed with streamlining in mind. Honestly, for me this BC is a great fit for the majority of my dives, if I may be on the surface for any length of time I consider it a MUST! When properly weighted and for me that means that I "weight out" as if I am diving WITHOUT a BC (may add an extra 1 lb or 2). I have so little air in the bc during the course of the dive that it is one of the most streamlined rigs i could have. At the surface I am as comfortable and stable as can be. IMO, too many people dive like they are submarines or floating cranes, relying on their BC's (wings too!) far too much. I believe that one should be weighted for NO BC plus a pound. This allows you to take full advantage of available lift if needed and you will be more stream lined during the dive as the bladder will have little if any air in it. When diving a backplate & wing you will find that less air will be needed to float on the surface reducing or eliminating the dreaded face forward force commonly applied by winged bladders on the surface. Using just enough weight makes for a better diving experience over all.
