A 32 would be too low for me and this terrain, FWIW I run a 11-28 on a semi compact 38/52 and like that extra gear for powering down a descent but thats about the only place you'll use the 11t. I used a 13-29 (campag) on a 30/34 last year for the alps (the marmotte) and whilst fine going uphill I would have liked that extra gear or two coming down.
