breck dominates the 4ft high rail category, haha. i really hate park lane though. the jump lines are both amazing, though freeways are a little better cause the steeper run makes speed more consistent, the medium line at keystone is way better than any of the jumps in park lane. i know you have a boner for breck, that's fine, lots of people do, though i think both have room for improvement (the potential of keystone could be huge if they maximized the space, didn't clump features, and used the half of the rails that they left sitting around in piles).
