I have the 2011 scratches which were called the s4's at the time and I love them, but the edge durability isn't that great imo. I'm 155lbs and ski fairly aggressively and I managed to bend/messup an inch of edge underfoot on one ski, which was later repaired, and later tore about 3 inches underfoot of my other ski. I'm selling mine to a buddy for dirt all because of this. They're excellent skis though, great for carving, holding an edge when undamaged, and have a very low swing weight, but personally I wouldn't use them primarily for rails. If you have your heart set on them or can get them for a great deal i'd say go for it, but if I may make a suggestion I'd recommend the K2 domain, solid ski I've used for preseason jibbing. Really tough, and so much fun, not as poppy but more pressy and flexy if thats your thing. They're pretty much made for all park, mostly rails.
