Starting by going straight up is, I would estimate, in the 5.7-5.9 range. It's more like 5.5 to go up on the left side (the blocky section, not the crack, which is too easy) and get onto the arete from there, and maybe around 5.6-5.7 on the right side.
As this route is not in published guidebooks, these ratings are just estimates. I am hoping that by giving this route some exposure, it might help lead to some sort of consensus ratings eventually.
