Starts just right of Animal Magnetism. The pitch has two distinct sections: a desperate bulge from bolts 2-4 and a slab/face/arete the rest of the way. The first section seems a lot harder than most (all?) Boulder Canyon 12a's I have done -- might be rated 12a in Eldo. The rest of the climb is a long stretch of countiously engaging (5.10 to easy 5.11) climbing on the slab/face with a couple of moves back and forth across the arete. The upper part is quite good on its own, worth pulling on the 3rd and 4th bolts to get to (as I did). Note for those allergic to pegmatite, the upper section contains some sections thereof. The route leans to the right, so the lower off ends up well uphill of the start, at the start of Cujo Tranquilizer, alleviating any worries about descending with a 60 meter rope. The anchors are shared with Cujo Traquilizer pitch 1, creating top rope possiblities.
A cool variation to this pulls the 12a crux then traverses left into Animal Magnetism... I think the guide calls in Cujo Magnetism or something like that. The crux is very technical and thin but didn't feel any harder than 12a to me.
Seemed hard for 12a in the opening. Good hands in the lay-away start, but marginal smears for the feet. After the fourth clip things settle down to thin, thoughtful climbing in a laboratory safe environment. The best feature is probably its length. A 60 meter cord just drops you back to the base.
I thought this climb was very high quality. The start is tough, thin, and the feet are tricky. There was at least one 11+ section on the slab, unless I missed something. This climb requires a lot of draws, 19 including two for the anchor. A 70 M rope is helpful if you don't have someone to follow the route to clean the draws.
A Boulder Canyon route that actually feels hard for the grade. I think the crux start is very difficult and hard for the onsight. Great climb, one of the best 12-s in B Canyon.
