Skiing has experienced a lot of progression in the last decade or so. Not only on jumps but on rails and out in the cities and towns where crews have been sliding hand rails for years. Now many people are just skipping the hand rails and sliding down stairs. It was in Ian comptons new webisode and I have seen it else where. It is my theory that these trends are actually inspired by ski companies to make kids trash their skis quicker so that they will need to buy more skis. Pretty much all of jibbing progression has probably been thought up by the ski companies(and illuminati) in an effort to sell more skis.
