i am not a fan of the whole lets spin a lot and just tap the rail... thats not really a rail trick now is it? however, 990 to rail takes mad balls because think about it an 810 is just a cork 7 to rail, and you have a lot of time to spot in a cork 7, however a cork 9 is going to be blind at the end, which is scary going onto a rail, thats sick, but i would still rather see somebody 270 or 450 onto a long rail and stomp it while showing they can slide rails too...
