ok, the tsi is aone pice deck you dont have to get technical with it, the poein of a one pice deck is conected som how to the nech so it doesnt woble, and anyways that doesnt matter, and other componies didnt copiy, tsi just opened the door to all these new posibilities, just liek one company started the one piece bars, and soemoen started the threadless forks+compression, and its nto copping its expanding our sport, we cantget to un simmilar with parts besides esteithics, and we are lucky to have the few one piece decks that we do, all the different deck are just slightly different for the fact that evry rider is slightly different. so shut up ND BE HAPPY. th reson all thee things are better is called innovation, NONE of the componies are trying to say theyhave the better deck, or an original deck thast all thier idea, anythgin sai dliek that is by the riders becouse fo thier own personal preferance the different decks are all improvements on an older desigh no improve to ALL riders needs, the more decks the better our sport and riders. YOU PISS ME OFF FOR SAYIGN THAT. im sure your COPY CAT FOR DOIGN TAILWHIPS, OR BARSPINS OR ANY OTHER TRICK JSUT VECOUSE SOMEONE LANDED IT BEFORE, NO.
