I shipped my equipment out to Vail prior to arriving for a few days of skiing. When I opened my ski bag I noticed that I think I put my helmet under the zipper of the bag and probably something heavy was stacked on top of it. Looks like the zipper put pressure on the helmet and there is a small dimple on the top (kinda like someone shot a bb at it). Not scratched just indented in that tiny spot. Otherwise it seems fine, integrity is ok, etc. What is the rule of thumb on replacing a helmet when there is damage or it has been stressed?
