the lab's are a little diff than the reg ones. according to the rep who was just here and explained it all, the dimensions are slightly different. they have the same core used in one of their race skis which has a little bit of wood combined with foam, similar to the thc concept i think. the base is more high maintenance than the regular base. it's a great ski, but dont take it on rails. but if you're getting it for 300 bones, get 2 pairs
