Don't forget the Proofide, or the special adjusting spanner, either. Unless you're of a whippet build, I'd avoid the narrower Brooks Team Pro. I tried one of these on another bike, and found it to be supremely uncomfortable. If I'd known about Scott Superblocks while I still had cantilevers, I probably wouldn't have upgraded to V-brakes. These give extra push when spinning up long hills, and allow quick getaways at traffic lights.
Clipless shoes are remarkably comfortable to walk in.
I'd forget I was wearing them, if they didn't creak so badly. The hand-built Mavic replacement was much more rigid, but the rim was overly light, and wore out in about a year. The lightweight Mavic replacement seems to be holding up well, even though I do most of my braking on the front. I guess the front doesn't get all the transmission grot thrown at it, unlike the rear. At the 8500km mark, the front chain-ring and rear sprockets had become so hooked that shifting was difficult.
