Mike Rusczyk and Justin Strubing were both years ahead of their time and stuck on Foundation when they were transitioning to SoCal handrail skating. If they came up now, Mike would probably fit perfectly on Polar and Strubing would pop up regularly in GX1000 clips.
Travis Erickson put out one amazing part and vanished.
Jeremy Reeves, and to a lesser extent, Russ Milligan.
Pat Burke has so much potential, but if he never does anything at the level of his Slave part, that's fine. That part is near perfect.
Jose Rojo seems to be incapable of passing Tiltmode punchline status.
I was always a huge fan of Jan Kliewer's skating. Did he peak in Europe?
