It influences my choice a fair amount. It has very little to do with the skier as a person, but the type of skier they are. If the guys ride like how I ride, or how I'd like to ride, I'm going to consider the ski. My decision isn't also based on a single pro either, more often than not its the entire team that might use the ski.
Mostly though, I base my decisions on design (not graphics) and flex, then possibily price.
