I had about 80 dives on my 2005 Black Diamond before I sold it a few weeks ago. My experience was that the rear dumps did not work that well for anything other than a head first desent. Now, with that said, you must pull the valve string up because pulling the string down (the easiest almost natural direction to pull it) pulls the valve below the air in the bladder. This might be something you can do on your current BC. I never used the chest mounted shoulder dump. I only used the inflator dump and it required re-positioning in the water to get the air out. I never used the pull dump as it broke and I never bothered to fix it.
The bladder never rode up over my shoulders, and it was a comfortable BC, but as you suspected, its bulky. The straps are not exactly straps that go over the shoulder, they are wide areas of fabric. It spreads the weight out well and keeps everything in place. I dove a drysuit at home and a T shirt on vacation and it always stayed put. When figuring out my buoyancy I learned it takes 5 pounds of lead just to get the BC neutral in the water. It also weighs 15 pouns, so plan on a heavy rig. The pockets are nice, but here in SO.CAL. we wear gloves, which makes it almost impossible to get into them. I considered installing grommets and pulls, but never got around to it.
