I don't get into the whole what pro is the best thing because they are all pretty badass. I do however pull for the local guys and 2 of my favorites to watch are Gabe Lucas and Tom Fooshee. Both throw down and I'm not even going to try to pick which is the better of the 2.
For the true all around rider, meaning cable, boat and obstacles then it can only be Tom or Nick. Tom possibly with the edge this year as he is dominating cable, but hard to count out nick with the most pure talent outside of Harley.
