Yesterday I managed to get this done:

I like it a lot, and I think it's a first, a pretty obvious left to right traverse of the north and then west faces. I quite like that it tops out, and I find the move transitioning from the middle of the west face, to get established on the crimps of Porter's climb, is really good.
Enjoy!
