I think it will be very hard for anyone but Americans to get into top 10.
There is perhaps a chance for Savoya, Y. Aigoin... or similar of getting here.
But the top bunch of Americans - Drake, Truhe, Maifield, Tebo, James, Cavaleri, etc etc etc I think there is nothing between them, so hard to say who will win. That is of course assuming they are all in the Worlds, not all the good US drivers got places
