Nope, not the 2012, I owned a 2011. Not really a fair comparison. I think the Evo you will definitely get more damping and ability to blast through variable conditions, but I like the Westmark for the feedback in jibbing. The flex points are different, too, for pressing.
I don't think you can go wrong with either. I like the idea of full rocker and if I can get the snap and grip without adding camber to it, I prefer the flex points and butterability of pure rocker.
