I've installed an Edge Pro on my Ibanez RGA42FMT, routed for the standard DL trem. It works terrifically, and fit into the cavity with no real modifications needed (My install guy did some slight interior sanding) however there is certainly a pull-up limit if you try to lay the bridge flush with the body. It doesn't take much angling to allow yourself to pull-up as much as you want, but I figured I should mention it for data's sake.

I installed a Lo-Pro Edge on a Puzzle RG that has an Edge Pro originally. I had to file the two "horns" near the knife edges to make them shorter (just like they are on the Edge Pro). The filing is not really visible or noticeable. Otherwise it fit like a glove. I also changed post mounts or whatever they are called. Pretty disappointed with Ibanez for installing the ones without a bottom to begin with.
