Replying to Which Skis.

Hey, just looking for some expert advise please. In your opinion which is a better one-ski-quiver for me the Line Blend 2009 with Marker Griffon bindings or the Rossignol S3 2010 with Salomon S711 Bindings. I like riding powder and park I'm a bit of beginner in the park can do some spins and standard grabs. I do a few small powder drops. I am about 5.9 and 154lbs. The Rossignol S3 are 177 and the Blends are 169. Would this influence my park riding at all? I'm used to riding shorter skis. In your opinion which would be better? Lots of people that I have asked seem to be saying the Line Blends based on the ski, my type of skiing ability and the size but I was wondering if I wouldn't be loosing out too much on the rocker-camber-rocker technology and early rise on the S3 2010 model as opposed to he cambered Line Blend.
Thank you.
