Not sure on the rocker, but they are totally different skis. Shogun is stiffer and more of a charging type ski. Kung fujas is mad buttery and has a much shorter sidecut
Just saying, the shoguns were a really disappointing ski, spent 2 weeks on them in blower pow to boilerplate and everthing inbetween and they were just so average. Only plus is that they are reasonably stable in soft snow.
