I am by no means an example to follow...but I went from a Senate to a Vapor Pro Build during the mass 2018 upgrade and took advantage of the 2017 used ski pricing.
It was like I didn't know how to ski
(check out this gem)
But precisely because it is less forgiving than my Senate (I never even knew what that meant until I jumped on the 66" Vapor from a 67" Senate) that I have had to work even harder on my form. You get instant feedback on the Vapor...rear pressure? Oh...that's ok Mr. skier guy, I am just going to stop and let you figure out what you did wrong while you gather all that slack that is about to go away. Balanced on the ski and good tip pressure in the turn? REV UP THAT ENGINE, WE ARE GOING FOR A RIDE!
