Different fit when bone dry vs. humid vs. wet. Saddle would sag in middle and get more uncomfortable.
Replaced B17 with Team Pro. A better fit, but still same sagging issues. Even just my sweat would change fit.
Rail broke on Team Pro after 10k miles or so. Replaced under warranty.

Now using a Fizik Aliante and it is more comfortable and consistently so with never a concern for the weather.
