Replying to Volk Step vs Atomic Punx vs Line Chronic

Getting a pair for Christmas and I would like to know which one pair would be best for mainly park. I'm 5'11, 128lbs and I would say I'm an expert skier. I want something relatively flexy but not crazy. I want to be able to do anything in the park, meaning both rails and jumps. I'm kind of against the cap wall on the Chronics but I could probably settle for them. These are the skis I've been mainly looking at but any recommendations would be nice.
