Let's get a ball rolling...

[Clayfighter]

Sketching like Skelli - Do a trick with the wildest possible sketchy landing
Corey's Challenge - Do a Corey Webster-pop to grind a handrail
Southcity Bound - Hardest line you can possibly muster up
Pawn-o-rama - Do a Pawnluvguitarist-inspired trick or line
Cookiesupporter's challenge - Do a realistic trick or line while going insanely fast
Skinny like Stevland - Gap something and land on a skinny ledge
Signed by the Guy - Do a frontside rock n roll
Like a Chief - Find and skate an ungrindable that hasn't been done

Whadaya think? Feel free to chip in... Just making some suggestions

I'm in for NOIR if this happens.

I'm all for keeping the "rules" generic and allowing for some creativity. Far less specific tricks, who wants to watch multiple teams/skaters hit the same spot, doing the same trick over and over and over again. What would separate one from the next?

Style. Filming. Creativity.
