Before people jump on me, I did a search, and have read about a dozen threads, but none really talk about the specific difference in the two besides the fact the AC50 is 85mm under foot and the Kendo is 88mm under foot.
I'm 5'10" and weigh 175. I'm level 9 skier, and will be skiing mostly in Arizona, but will take trips 1-2 times a season to Utah, New Mexico, Tahoe, etc. (all the stuff that is a day's drive from Phoenix for a week trip or so).
I ski mostly front side, and love to rip fast, slalom turns on the groomers and in the crud. I don't ski much powder, mostly because I ski with my family, and they are still beginners for now. So what are the pro's and con's of each of the skis? My only worry about the Kendo is they won't turn as fast as I might like.
