I don't know a lot about it but ask around a lot of people have done it.
This was the first time for me and the second time for Tim but a new variation. There are a couple lines right and left. The right is obvious ie stay right and then the other is up through the rime and gullies and stays interesting almost all the way up. You should probably have a pic of the gullies and description for the left, but you can tell what goes through once you've headed into what looks most interesting. You want it cold for the left line though cause there can be a lot of ice and rock fall. Hope that helps,
