Weight appropriate for wetsuit?

[Swimjim]

I am the same size and weight as you and with my 7 MM wetsuit I use twenty eight pounds, so I'd say your pretty close.  My  BC carries ten pounds non ditchable, so My weight belt has eighteen. 
      I am currently transitioning into a bp/w set up and yes the backplate does weigh a few pounds so that can come off the belt.  And when I dive my old steel 72's as independant doubles I can lost a few more. 
      At anyrate, your pretty close.  Take a tank with 500 psi in it and do the bouyancy test.(In a pool or controled environment.)  With no air in your bc you should float vertically with the water level at eye level.  Dive safe
