i think what people mean by core is companys that make only twin tip skis so the money stays in the industry, when you support a company like rossignol your not sure if the money from the skis is going back into the development of twin tips or newschool skis. It could just be going into new innovations in there racing skis. Whereas a company such as Liberty, 4FRNT, Armada, Ninthward, ect. are all considered core companys. When you support these companys the money is going directly back into the industry to fund there riders, new development, products, events, etc. so pretty much putting more money back into newschool skiing and skiing these companys support.
