I got them at the end of last season and they are fucking awesome!!!! I skied them about 15 days late season in spring conditions at Sugarloaf Me, and Tuckermans Ravine. I demoed a bunch of other skis earlier in the season and previously rode the line prophet 90s and the rkrs are hands down my favorite skis I have ever ridden. Despite their width they rail trenches and have unreal edge hold on groomers. They are actually the most fun skis on groomers I have ever been on. Their flex profile is perfect in my opinion with a tip and tail that are more forgiving but a fairly stiff midsection. They are super responsive and bounce you through turns but also feel very stable and smooth at high speeds; no tip chatter at all. They do prefer to be ridden with an aggressive forward stance and need some speed to really get em working. They perform great in the trees given their relatively tight turn radius and are easy to throw around in the bumps compared to others skis in their width range. I haven't skied them in pow yet, but they performed amazingly in spring mashed potatoes. They cut right through heavy clumps of snow without being thrown around and were once again very responsive yet stable. As far as park riding goes, their recommended mounting point (where I mounted mine) is fairly far back but I didn't get these for the park. However they were still fun and stable on jumps and skied switch pretty good for being mounted so far back. I would suggest mounting them at the recommended line because that is how the ski was designed to be skied. Also the 13/14 graphics look so dope. The only thing that I don't like is the vertical sidewall construction makes the top sheet chip a bit more and they are so pretty that I don't want them to look used, but that is just because I love them so much.
BTW i am 6 ft 180 lbs and ride the 181s. The 181s are great for all mountain east coast riding, but if you are out west and are my size or bigger id get the 191s for the added float. The 181s feel perfect for me though and I don't know how different the 191s ride.
Just get them. they are awesome. most fun I've ever had on a pair of skis.
