Since the new cranks, have you put on many miles without this pain? Depending on what you are wearing in the cold, a few layers will raise your effective seat height, compared to warm weather and just shorts. Sounds like you are getting close to a solution.
Since the new cranks, I've put on about 450 miles without pain.
I'm going to use my cycling shoes at tonight's class ... the pedals there have SPD cleats so I'll try my shoes with those pedals and see what happens.
