It pains me to say this but I really like Rapha chamois. It pains me because a) their catalog copy is SO pretentious and b) they're so expensive. The shorts are quite long (close to knee-length) and the capris are also fairly long, and the waist material is very comfortable. They are by far the most comfortable long-ride shorts and capris I have. Perfect for PNW weather, so I would think they'd work for your spring and fall weather as well. I can't do bibs because I pee more often than anyone on earth. This info is just in case you decide to give up on the bibs but are still looking for moderate/cool weather capris. I too hated the Ibex chamois in their capris, by the way.
