The fall from the final move has been well tested and with a good belayer should be safe. (being a scaredy cat, I used two belayers, each on a half rope for redundancy). George Ulrich's GriGri in a ground anchor would put a lot of shock load on both the gear, leader and ground anchor - most people would chose not to do it this way.
The move to the shotholes is hard and very highball, this is the major risk for most people, even with pads.
I found leg flexibility very useful - get stretching.
At 'the Edge' wall in sheffield there is a Masters Edge tribute route to practice on. Presumably it was set by Tom or Pete, it is almost as hard as the real thing, and has a scary last move too!
