It was a dramatic snowboard competition at Spinlderuv Mlyn today. The best tricks in the unique super slopestyle contest were performed by finnish rider Markku Koski. He won the Quiksilver Snowjam, which is the final event of the O2 Snowboard Tour - one of the biggest Czech snowboard events. This means that Koski can add to his biggest successes from this year yet another one (after 6th place at Half-pipe competition at Winter Olympic Games in Vancouver). Czech rider Honza Necas finished in second after with a good-looking double backflip at Big Air. Swedish rider Stefan Karlsson came in third place.
