It is an ok route, short and picked out...we all took turns leading it. The mixed climb next door (La Punta Blanca, M6-8) was a blast.
This was one of the first ice climbs I followed, back in 2006 or so. I've led it twice since then--in February 2009 and January 2010.
Doing it in one pitch is a lot of fun. This is definitely one of the best routes in the canyon, in my opinion, and possibly THE best single pitch route.
