Ben, the only thing I didn't like about the way you have it configured is that when the bridge was weighted, for me, it cammed the plates outwards and the knots inward, making the knots hard to see, and the bridge adjuster straps/ leg loop straps all got a heavy kink in them.
Looking at your set up, if you think of it with the holes numbered 1-4, with the bridge adjuster being in hole 1, the bridge in hole 2, leg loops in hole 3 and the big hole as 4; It might be worth trying it with the bridge adjuster straps in 2 and the bridge in 1. That way when you hang suspended the harness workings are actually underneath the bridge, also everything will lay inline better IMO.
How are the surfaces on those PAWs, nice and round? Petzl usually makes great stuff and the red looks nice!
Hope you like the conversion, I love having that extra attachment point up front.
