Dr. Wayne Tomasi has some beta in Grand Canyon Hiking Adventures - South Rim edition on page 252-253. I'm not going to type it all out here. If you're hiking the South Rim you should help out the Tomasi family and buy the book. Also buy Grand Canyon Summits Select by Aaron & Pernell Tomasi.

Rich Rudow might have good beta. I don't know where he's hanging out these days.
Todd Martin might have beta. It's not on his website so he might be saving it for a book.
