I think I knocked this ski against a gate this weekend. The topsheet ski appears to have split around the outside tip. I think it's just the topsheet and perhaps a layer underneath that's cracked, but not the edge. Should a shop be able to fix it? Can I fix it easily myself? Do you suspect there's more damage than just topsheet? Lastly, what if I just ski it and don't bother fixing it, or just break that top part off?
