In reply to JKinsella: On the desnivel website:

Chris says: it is not the hardest route route I have redpointed, but certainly my hardest experience. It is a problem of resistencia (power endurance?) (I tried Capella one day. It is very hard: bouldery, not resistance.)
If he downgrades it to 6c I might have a go.
The video I found extraordinarily beautiful, the movement.
