It's worth noting that the original line on the first pitch stepped right at the third bolt, but that was prior to a loose block being cleaned. I revisited this route a couple of days ago and this move still goes, but more likely at hard ten or 11a. To keep the grade at 10b, swing out left to easier holds.
Never having climbed the route before, I *thought* the crux was a little testy for Boulder Canyon .10b. Hard .10 seems right for the step right in Ron's photo. Thanks Michael.
The first pitch and the first 1/3 of the second pitch are really nice: devious climbing that doesn't end at the third bolt crux. 2 1/2 stars (can we give half stars?)

We stitched the two pitches together to make one, long wonderful sport climb at near 60 meters. It's worth doing only if you don't mind the full weight of the rope at the top as well as have ~20 QDs in your possession.
I didn't read the description very well and went right onto Tag Team after the 5th bolt on the 1st pitch so I'll have to go back and do it straight up. The crux at the third bolt can be climbed 10a by staying to the right of the bolt, or if you use the holds on the left of the arete I thought it was 5.9. Of all the pitches I've climbed on Tonnere I felt this route was truest to its original grade.
