Is it me, or it should be Less Friction - More Speed? Since Friction will actually slower you, otherwise all diskbrakes (weird example) will not work... After all, longer skis should have less fristion due to their surface.. That means they will go faster and will be more controllable at high speeds since will have more "leverage" to go straight. That will also mean they will be harder to turn. Good example is Short Slalom skis and Loooong Giant Slalom skis.
