I just bought an M-107 with the fixed bridge, and I'm actually liking it more than my Universe! I say this because even though the Edge/Lo-Pro Edge trem's ARE nice, I'm just getting sick of having to deal with the headaches involved with a Floyd Rose. And whatever you do, DO NOT try to intonate a Floyd Rose by yourself. That is THE BIGGEST pain in the nuts. The fixed bridge is nice where if a string snaps, you can still finish the song without the whole guitar going out of tune, you'll get more sustain from the strings going through the body, and re-stringing is MUCH easier than a Floyd. And as far as my ESP goes, I'm dropping in a set of EMG 707's, for the thickest chunk around. I've painted a white stripe around the body & headstock to look like Dino Cazares' first Custom Shop Ibanez (hehehehe)! I'm starting to like the ESP's better overall, considering Ibanez keeps putting out the same ol stuff year after year.
