I've played guitars that were equiped with
Edge Pros, Edge Pro IIs and Edge IIIs and even a novice can tell the difference in the fluidity and smoothness of the Edge Pro as opposed to the other two. Of course, the Edge Pro II and Edge III aren't bad trems. They're better than those Licensed Floyd Roses that you'll find on Jacksons. Oh, and the Edge III may not be as low profile as the Edge Pro/II but it is still lower profile than the Original Edge.
