Depending on the manifold and bands you are using to double them up and he weight involved, you should be within 3-5 lbs between each set up. The LP50 tank buoyancy is -2.43 full and 1.24 empty, the HP100 buoyancy is -8.41 full and -0.59 empty but you will have the added negative of the manifold and bands. If you have any other questions, please feel free to email me direct at augiej@diverightinscuba.com.
