Matt, I made a little tweak to the main page. If you have any route notes or tracks, please note them in the additions section for the south ridge route page and I'll incorporate them where it makes sense to.
On the route page I have notes about what I did but also have notes by the original page author, as his course both on the approach and at the summit was different from mine.
The crux of my route to the summit, which was more direct than his, was definitely Class 4 and maybe even 5. But he went north past the summit and then came back to it and what sounds like easier ground.
