I thought the JJ's were just fine in everything. a LITTLE squirly at very high speeds in crud but if you're on nice groomed trails i liked them just fine. no issues going super fast and laying down nice turns, they're easy to spin around and slide and such cause the rocker and where i've skied them I never lost grip cause of a lack of edge contact. If I lived out west, i'd own a pair for sure. I ski these for a couple days every year out of choice when I go to CO to ski.
JJs are so sick dude! I have rode them for 5 years and loved every pair I got. They work the best while your chest deep in tight trees but perform amazing awsome on hardpack. A great all mountain ski. Do anything from bumps to groomers to pillows to bowls. If you like making bigger turns or go balls out I suggest the Magic Js they got more contact thus giving better control at higher speeds.
