This is a great route and provides a great feeling of accomplishment when done in a single day from Lupine Meadows. We brought a single 60m rope and could never find the alternative rap point. We hooked up with a soloist also carrying a 60 to make the rap in one shot. The rappel can get really backed up, especially with weather moving in.
The Exum is perhaps a bit more intriguing, but this climb is a classic and keeps you thinking on the way down if you don't repel (which also requires thinking. I recall giving up looking for the anchors and descending Owen's the first time. I'm not sure which is best?
