I agree Browning would have done fabulously under COP, but I think so would Stojko. Much like Slutskaya, he was not traditionally "artistic" but he had absolutely solid skating skills in all areas. His spins were fast and his almost eerie sense of balance meant he would have been able to handle the position changes etc. He had great speed, the best flow out of jumps I've ever see, and was able to pull of the quick difficult footwork. One of the things that made him so successful was his consistency.... he and Kwan, I think, are the two most consistent skaters I've ever seen — rarely did either make a big error. Stojko had absolute focus during his programs, and I think could easily have handled the more complex choreography that has come about under COP. Plus, he had those consistent quads.
I think both B/S and S/P would have fared well under COP. Dimitriev and both his partners would have done well, as would G&G I think. Ilia Kulik would have done well. Paul Wylie.
