I originally had a 50/34T compact and a 11-32T cassette. I'm mid-50s, probably 200lbs with my clothes on, and broke my ankle a few years ago. To get up Alba (comparable climb -- a bit shorter but a bit steeper -- rated as less difficult on the links I posted above), I needed to go to a sub-compact crank and 11-34(36) cassette. My kid, who is only 10 lbs lighter but vastly more fit and 21, can fly up that hill with a 50/34T and 11-32 cassette with no drama. So in addition to weight, fitness, age, injury history, etc. can all be factors, but lower gearing can only help at this point.
