I did mine the same as I do my 85's. just added 2 lb wts on each one. I also had 2 lbs on each side on my shoulder straps. This was for wetsuit diving.

A seesaw is a DRASTIC over-simplification of the concept....but I think I have figured out the math that would support extra tail-up trim using a heavy first stage. It has to do with the center of buoyancy and the center of gravity shifting further apart, creating a large moment arm about which the tail can swing.
As for reaching door handles with both hands: I just remember what goes where. In a cave, my safety and my primary are on my left while everything else is on my right. In OW, my SMB and spool are on my right and nothing is on my left. My tail d-ring is hard for me to reach, so I ignore it almost completely. Overall, I agree that a buttplate isn't necessary on a warm-water rig....and that is NOT a rig optimized for steels (23# of lift is pretty low for steels. Manageable, but low).
BTW, you would need to compensate for more than just the negative buoyancy of your tanks. You would also need to compensate for the POSITIVE buoyancy of your empty tanks. Overall, you'll need to compensate for the total buoyancy swing of the tanks you'll be carrying. An AL80 has a 4.864# buoyancy swing (assuming 77ft3 actual capacity, usage from 3000psi-500psi). That means you'd need over 9# of lift for two AL80s.
So her it goes guys, i have made some edits to my rig and thought i would share them, i made them about a month ago and have given it 30-40 dive's and am happy i have added (as suggested ) some d-rings on my harness at the waist, frontish , and now i have two clips on the cam bands on the tank and i clip both one on the but plate and the other on the waist the tanks don't move even when i swim on m back or any other position, i am even considering trying to take the 700gms of the tank and seeing soon, but i guess we will always play with our gear and try and find a better and better way to have it all sit thanks for the feed back and stuff

I'm gonna leave this here, just my opinions etc.

What, if any, is the down side to using both a front and a rear clip at the same time other than the obvious that you have 2 clips to work?
