1. Timber Gap - Black Rock Pass, then Lost Canyon trail to Sawtooth Pass (clockwise loop)
~28mi, 9300' vertical
2. Franklin Pass, then Lost Canyon trail to Sawtooth Pass (counterclockwise loop)
~28mi, 8000' vertical
Which has better scenery?
(If it matters, I'm thinking early September, i.e., this weekend.

On the first option (North loop), I don't know if I would take the side trip to Big Five Lakes or not. From Sawtooth Pass I'd probably climb Sawtooth Pk, then drop to Monarch Lakes and Crystal Lake before regaining the trail.
