[updated]
Big Up production report they filmed Chris Sharma sending his project at Clark Mountain! It's called Jumbo Love [5.15b], and it's probably the hardest sport climbing route in the world...

You know, this gigantic route featured in King Lines (Big Up film about Sharma climber's life), and where Chris takes huge falls in a massive overhanging wall ?

It's without doubt Chris' hardest route ever. Congratulations, Chris !

More info and a few pics on Big Up blog (via Climbing Narc).

Check out the trailer of King Lines, where Chris is trying the route...
