Axeman, you also need to factor in the change in buoyancy as well from a full tank to 500 psi on the E8-130. There is a greater swing than with an AL80. That extra 50 cf makes a difference.
I know from experience, although I went from AL80s (catalinas) to E7-120s. dropped a good 8 lbs off my weight belt.
