@Karlbach I ski on a SenateC and preferred it to the original, it just ran smoother for me.
I bought mine a couple of years ago.....I tried the P-6, Theory, Freeride and the Senate alloy and graphite.
For me the Senate C was a great intermediate ski and will last a while.
If you can afford the extra 100-200$ to get the C, I think you would prefer it.
