I'm not sure how to block an Edge Pro... hell, I'm not even sure how people block their Lo-Pros! But here's how I blocked my Lo-Pro 7 trem.
Took half of a wooden clothespin (the kind that clip, with the spring), cut off the very narrowest inch or so, then glued that, I believe sitting width-wise, instead of narrow-wise (you'd know by the angle of the trem which is right), to the front inside of the trem cavity, between the
trem block (where the springs go into the trem) and the body of the guitar. Tightened the springs up just a bit, and it actually puts it JUST right, in a perfectly level position, where you can tell by the very back of the trem. It ends up sitting perpendicular to the body (I think that's the term.
Parallel, if you will), and the trem baseplate slants up like it should.
