Replying to What Ski? K2's or rossi

I've been looking for a replacement for my 2010 volkl walls. Narrowed it down to 2. 2011 k2 domains or 2012 rossi scratch. I want something strictly for park. Lotta jumps rails boxes etc. What would be a better option? In terms of durability, pop, (not to buttery but playful, less stiff than the walls) stability. Price under 600. If you think you have better ski in mind than the above listed feel free to tell me all about it.
