Replying to Rockwell vs jmo vs whatever

Long story short, broke 2 pairs of jmos last year, absolutely loved the ski. Got a good deal on Scott jibs over the summer, rode them twice and absolutely hate them. So now I'm looking for a new ski, I have the money for another set of jmos, but I'd rather not spend $650. I found rock wells on theclymb for $450 and figured its a good deal seeing as that they are fairly close to jmos in specs. What's the pros/cons on the rock wells? Can anybody who has used both skis compare them? Or is there another ski out there in the under $500 range? I'm 6'4"', 190 pounds, I ride super aggressively, I live in Michigan so it's just park, ice, and groomers. Need a ski that is at least 181, 90-100 waist, somewhat stiff but not a 2x4, rocker is definitely preferred. Help me out NS!!! ++++k for help
