Although it isn't part of the original topic -- Yes, I have thoroughly tested the various Brooks models. Wallbike is an excellent shop/resource. I wanted the Swift and Swallow to work and I gave them lengthy, extensive trials, but they were torture for me. I have also tried a number of the narrow plastic saddles over the years. The Team Pro fits just right.

And, also off-topic -- I'm as light as I can get without losing more muscle/power. This is the first year I can say this with scientific testing to back it up. And I've lost another two pounds since I committed not to lose any more weight. Very frustrating. (And a problem I've never had before.)

So, now it's time to drop grams -- Brooks Team Pro at 530g vs. Fizik Aliante at 199g. My saddle is the only weight extravagance I have allowed myself in recent years, but 331g is a pretty substantial difference -- too big to ignore anymore.
