Dammit. I keep messing up at zone 67-68, the speed doesn't overwhelm me but I keep making mental errors and choke at the 2-3 laps of mach1. The worst part is that I have to go through 10 minutes of slow-mo boredom (Zone 1-50) just to practice on 60. I've died on Zone 65-68 on my last 8 attempts now.
Once I get Zonezues, WipeoutHD will finally be transcended. Then it's on to Burnout and Buzz.
