those are completely different skis you're talking about. the yard and urban rise are park + pipe specific and the MSP is a all mountain/ backcountry ski. if you're looking for a park ski the MSP definitely isn't it.
unless you like real stiff park skis i would not recomend the MSP. and i haven't heard much good stuff about core-upt so in my opinion check out the TNK or the STL.
