Nang 

In the guide book it says to walk off this thing. Has anyone done that? Looks a little stressful.

The walk off to the east is pretty casual, as I recall

I guess they added bolts to the start of "My Mother the Rock". We ended up going up that thinking it was "Nang", but thankfully my partner had plenty of gear, because it's a good 30 feet of sustained face climbing from the third bolt to the fourth bolt under the chimney. Then he trended left and joined up with "Nang". This variation is a great climb in its own right.

If you want to do "Nang", make sure you get on the second bolt line from climber's right. That's definitely the only one of those two lines that fits the "gear-optional" description.

On the walk-off there's just one step-across move over a 3-4 foot gap that requires a little attention but is easier than it first looks, then the rest is casual. Once on the other side, you stay towards the outside and end up over by the anchors for Agatha Christie on the North Fin (for those who want to leave packs at top).

The extra bolts right of Nang are my fault. They were the result of a mixup as to where "my mother the rock" really goes. It's not where the book says it is, but after it was all said and done, Todd Bibler said I should leave the bolts, so I did. FWIW, I think it ended up a really fun (now mixed) route (there are four bolts over the course of 150 ft.)

Didn't bother me, it's a pretty cool variation actually. I haven't led it yet, but from following seemed like really cool 9+/10a moves over good gear, then you can finish on Nang on the tower by extending the 4th bolt under the chimney and the first bolt on Nang itself.

Seems like the R rating on "Mother" would be from trying to protect the really thin seams at the bottom, wherever they may be (near your bolt line or further to the climber's right).

Awesome climb!! Really long with great movement and solid rock the whole way. The walk off requires one small jump (a few feet) but is otherwise pretty casual. 13 bolts plus two shiny new ones up top for belaying your second.

This is an absolutely brilliant climb. Best route our family did in a week of climbing here at Mt Lemmon. Has a bit of hard slabby crimps, a little runnout to keep you focused and ends with awesome overhanging jugs. A classic and memorable 5.10 for any area. Do it.
