considerations on buying a saddle
There is only one saddle to consider, Brooks. Don't sell your soul to the god of Style and buy some ridiculous piece of plastic. When your sit bones are chaffed and sore at the end of that Metric you'll wish you bought the heavier Brooks.
Give it the ebay test. Have you ever seen any of those plastic saddles selling used for what you paid? The answer is NO. OTH, used Brooks fetch the same or more than NIB Brooks. It is the only saddle I've ever seen that used versions bring a premium. If it weren't a desirable saddle, people wouldn't be buying them. See how much used Fizik's go for. Good luck in whatever you buy, but keep the Brooks in mind.
