I have now ridden all three varieties of nomad, the sft is my favorite. I rode the rkr one like two days ago, it's kinda weird at slow speeds but once you pick up, and if you're not a noob, it turns fine. Didn't get to ski any super deep stuff, but I found stashes of pow and it floated fine. They have a very firm and poppy flex for me, and the rocker made it easier to ski and jib around.
Although, I'm quite light at 120lbs and 5'5". So perhaps it acts much differently under somebody heavier. I rode the normal stiff ones and while they turn great and feel very solid, I prefer something more jib orientated and soft. Under my weight, the stiff ones really feel poppy though. I would nollie off things and get scared because I got popped up so much. I was on 168 sfts and normal nomads, and I think 171 rkrs. I think if you're bigger than me or like a stiffer ski and are light, then you'd like it.
