I worked a year in a bike shop that was the showcase for the Fuji distributor in the '70s. The Fuji touring bike had a near copy of a Brooks. I picked it up and used it several years on my commuter. Very high quality seat. Just wrong for this ex-racer who sides forward and back and uses all the real estate the seat has to offer. (Rivets under the perineum get old quite fast. The leather on steel back wasn't a whole lot better.
But that seat opened my eyes, Brooks is not the only one that can make a good seat.
