If people are looking for all around best am, i am goign to have to say Alex Martini
He killed it this summer in whistler with steezer tricks than most of the pros in high norths lane on the big table
(ewok grab)
He killed urban all year(some gnar rails), and is in my mind one of the best urban skiers today (alot of poeple would agree with me on that)
And he has a racing backround (7 years) so he actually knows how to ski unlike alot of park skiers, and can kill it on the steeps and pow, in jackson hole the year he held it down, and he isnt afriad to try some ill cliffs
(sorry no back country photos)
Now oviously he isnt the best at park, or rails, or big moutain, but he is pretty sick at all of them, so i would say he is definatly a solid canidate
Others i would include would be Clarke, Walker, Cosco, David Beliuea(sp?), and Andrew hathaway (nice jumps), and definatly Amhet holdin it down on the urban scene
