About the jumps, this is because of the slo-motion in the LP at Worlds. I've noticed a big move of his shoulders before the 3Flip and the 2A/3T. But it's in slo-mo ! That's not a problem, but I'm afraid because while growing, it gets rarely better. Anyway, I like him. I've been impressed by him at Nationals. I think he is interesting to watch and to follow.
