I received a reply directly from Jeff Zeagle. He and his contact are thinking it is "in the range of 1-2 lbs". Pullmyfinger, I really would appreciate if you could do a sink the bcd test at the pool. I just think it would take more than 1-2 lbs to sink my Ranger. It's a medium BTW.

In case anybody is interested, the reason I'm wondering is I'm thinking of purchasing a BP/wing. I wondering how much, if any, weight I might be able to loose from the rig. I don't mean 6-12 lbs on my back from moving weight around to different places. I mean total carried weight. If the Ranger BCD is , say 5 lbs to sink it, I would then be able to drop ? ( some ) weight if the wing/harness ( not with the BP ) of the new system sinks with less weight. That's my thought process. I have been told ( 2 people now ) that I won't loose any, but if the buoyancies are different between the 2 set-ups, I should be able to loose some.
I weight 150 lbs, drysuit, I'm at 32-34 lbs in fresh water and an AL 80.
