OMG, he has everything going for him-from the jumps with great flow, BIG personality, to strong fundamentals, incl. the edge quality and agility. Without the trouble on his flying camel (which prevented him from earning much GOE on it), he would have broken his previous SB!
Sanchez is a bit older, I think they have very different styles. Sanchez has more strength, while Sena has more ellegance. Just my opinion, but both of them are very talented young men.
