Cdarmy: While this was a fairly plain tank bump in terms of landing and the spot in general, that was some seriously nice rotation, which is exactly what was being looked for in this challenge. This is a good example of fitting a stunt around a challenge rather than fitting a challenge around a stunt, which I think is very important.
NuclearDeath: While this was a nice tank bump spot, I think most people would agree that it needed a better ending. Also, while there was some rotation I don't think it was involved enough in the stunt.
For the mad rotation I vote Cdarmy.
