That "expression" is what I think these guys seem to lack. To me it's like they have seen what Danny does, make a check-list then go out and cross them off.
I know it's hard to come up with all new stuff, and that's why Danny is one of the best because he came up with some unique stuff (or at least took some older stuff to bigger extremes). I take a lot of influence from bmx vids as there is plenty of stuff they do that can cross over. I always think fewer tricks but done with more flow will always look better, and that's probably why I really like riders like Chase Hawk over people like Mark Webb.
