@abski, the reason I chose the Vapor over the Senate is due to length. I like a 66" ski, and the Senate only comes in 65" and 67". With my weight and ability, I was right in the middle of the size chart. I really didn't want to go back to a 67" ski, this is what I used when learning the course. I always had to mess with the fin to make a 67" turn. I thought getting a 65" would negate the extra width of the Senate.
I went with the Graphite knowing that at my age, I really don't push it anymore and thought the Lithium might be overkill. I just go out and enjoy running the course and the speeds/length I know I can handle, and ski smoothly. Also, the price was great!
I might have changed my mind if I lived somewhere that was convenient for demoing skis....
