They have edges on the fragile side, so if it's going to be strictly a rail ski you might wanna look elsewhere. However, I have a pair that I use for pretty much everything (little park and all mtn skiing) and I love them. They have an awesome flex profile that I've come to really enjoy, nice n stiff underfoot with super soft tip/tails (but not too soft so much that you'll wash out). While that flex sounds typical of any ski these days it really is awesome how pinpointed and dialed in it is on this ski.
