Misha, I don't know which way you guys went, but the easiest way to reach the summit seems to be traversing to the left and up the class 3 slabs on the left side of your photo. I'm writing this because it wasn't so obvious to us when we were standing there. Fortunately Scott Pierce suggested going up those slabs and it was an excellent choice.
That's pretty much what we did as well. Did not follow any particular route beta; just went with what seemed good.
