I have no used them in the park, but these and Armada Alpha 1's are two of the true park skis that i can think of right now. Not sure if the alphas are symmetrical but i know the Rockers are. I've heard nothing but amazing things about the Rockers and I'm def gonna pick up a pair eventually
hah my girlfriend is gonna get so wet when i tell her this - dilla_says_go
If you have a more jib oriented, playful style of skiing, go with the moments
If you want to charge a bit harder, and have more versatility, go with he kung fujas.
Personally, while I think the Moment reno rockers are amazing, and one of my favorite skis, they are Def no a one ski quiver, and can be kinda sketchy on icy conditions and larger jumps. But they are oh so fun.
