All 3 are gonna be nice for rails, Id say the ARV will be just be a wider platform and better for jumps and all around skiing the mountain, however, the TWP is great for rails considering Its a mostly camber ski compared the heavily rockered Magnus and isn't too soft for jumps. The Magnus will be a more surfy, rockered option that I have heard is a mad fun ski. All 3 are pretty damn good durability.
