Replying to K2 skis yo

So I'm 5'11 and have a killer deal in the waiting on some 2011 recoils. The problem is, I'm not sure if that the 169 size I can get them in is going to work out. I would only ski park on these, and would mostly be hitting 30-40 foot jumps and rails. I'm not very aggressive in the park, and 140 lbs. I haven't tried these skis out center mounted yet (where I would be skiing them). Anybody here have any issues with them? I've heard the weight is pretty bad, but I can deal with that.
