There is no more spk, thruster, foil skis...the only ones that seem to have been brought back from last years is the Rocker, Gun and Dumont.
New Salomon skis...Czar,Lord,Suspect,Threat,Mai Elai...
The change in flex can also be because they've gone to all wood this year. The first year 07 Dumonts were a combo/partial wood core like this year's thruster 08...this years 08 dumont is full wood core..and I assume that the flex is even different for this year's 08 dumont and next years 09 dumont.
Another possibility is that Simon uses a 181cm ski in the pipe and a 176 in slopestyle. The length may not yet be available to him in the 09 dumont...same as for Sammy.
