They are similar to PST 119's, so I have not tried the 119's. I also have 130's, but they are longer and my thought was that they would make the problem worse, not better.
I have the tanks about as far up my pits as I can stand. I can move them up a tad more and will try that. A buddy once used two ankle weights, snapped together to create a neck-weight! I haven't tried that yet either!
I can also move the wing down, maybe. It's pretty far down, like the pictures shown in Jason's thread on sidemount, including the strap that holds the ends down around the hips. However, I put the wing on the outside of the harness, not on the inside like Jason did....
I was wondering if on the inside of the harness it may force the air lower in the wing and not let it collect up higher? I put it outside because I was worried about getting enough lift with stages too. Guess I'll move it to the inside and see if that helps.
