I've got the Cutter knicks, too. I like the fit, but I don't like the way they're pilling up in the frictiony spots.

Last week, I bought a pair of nylon/cotton Cloudveil (very good quality) 'long shorts' from Marshall's discount clothing for <$20. I rode 60 wet, rainy miles in them on Sunday and 11 to work today and I'm thinking I like them a lot.

Mesh pockets, zipper thigh pocket, knee coverage, fast drying, and comfy over undies or bike shorts (or nothing at all!!).
Also they're dark gray so 'Brooks Butt' is minimized. I'm gonna shop around for another pair.
