I finally decided to try the elf shoe park skis after many years of thinking they would be unnecessary and awkward. I got some used original Alphas, which are probably most like the new Halos. I must say that I love them!!!!
Initiating turns is amazingly easy. I have never had as much control over my skis when I was riding through crappy snow + mogul filled steep runs. The ski turns exactly where and when I want it to. The light swing weight made all my rail tricks come around much more consistently. I was afraid they would be unstable at speed, but they do not feel short to me at all. I am used to riding ~181cm skis in the park, and the 182s give me all the same support. I landed off center on jumps and never felt unstable for a minute. They also never feel "stuck on edge" and give me a struggle with an awkwardly weighted landing. I am never going back to regular camber park skis!
