Well IIRC he didn't really mess with his balance and weight distribution, as he wanted it as close to his old Kramer as possible (correct?)
So it could be that those Greg Raven specs are indeed unstrung, as the 379 SW seems more likely considering how much lead he placed at 3 and 9. I myself tried the same amt of lead on my BLX90, and it felt more like 375+ than 367 (similar to how I had my Radical set up at the time)
