I have a Senate-C i picked up last year. I think it's a great ski - i ski about 6 sets per year in the course and ran 28off at 34mph full pass last year and couldn't run close to 22off the year before on my connelly rocket.
If i could do it again, for the price point, i would stay with the senate-c or would maybe have demo'd a vice.
Plus, with strada bindings, you have a setup that will be greta for a while.
