I agree.
Most of the finalists are incredibly talented, but that's not the point anymore. No TW or HH imitator will ever be better than the actual TW or HH, plus if their only power is doing 1000 differents tricks, they are not special since the skiing world is full of riders that can do 1000 tricks and stomp them. If not today, maybe tomorrow.
The important thing is to have something new, to add a different and personal style to the skiing world. That's what Corey, Clarke and Tom did, even Brogan with his exhagerated afterbang. And I think that Luka is the one that has a new&fresh personal style with the talent to learn and progress.
A part from that, trickwise, I think that Chris Laker is a machine, reminds me of Kenworthy. Seem to be able to do all the tricks in the game and learn any new ones in no time, and that's amazing (plus he's only 15), but I don't think his style adds anything new to the sport.
