I don't really like Hydra stunts. Even if the ditching made the hydra grind all the way through the rail, I just can't see these ditching stunts as skill-demandant or even good-looking. In the other hand, Gryzlek landed some sexy grind there. I don't know if it's a new stunt or not, but it sure requires a perfect execution to even get the distance to the cannon right, and then getting the angle to the grind right. I must say that it's one of the few stunts so far in the tournament that impressed me.
Good job, Gryzlek, you have my vote.
