Park:The magnatraction (wavy sidewalls)make skiing on ice/pipe a lot easier but it also makes it easier to catch your edges on railsBUTthey were freeso just detune the edges if that hasn't already been done (if you are using them for park) and trry them out for yourself
I ride a set of LIBTech NAS' and they handle pretty well in the park, if you really need a had turn though your shit outa luck, even with the magnetraction they have a wide turn radios
