From what I remember reading on here the edge 2 and 3 are not very good trem systems. The edge pro is great, original and lo pro are great as well.
I have a js100 that had the exact same DL bridge you have in your guitar. I wound up putting a gotoh ge1996t in it. You can find them in chrome on eBay for around $130 USD. They vary in price a bit depending on finish.
Gotoh makes the edge trems, and this thing is excellent. It's a drop in replacement if you use 10 gauge strings. If you use 9's, the Allen keys that crimp the string in place will have to sit further back to intonate properly and will hit the body instead of pass into the cavity.
