I’ve come to the same conclusion as the OP about Brooks saddles: too variable between what should be identical saddles (no two cows identical), too much maintenance required and not worth the half a kilo it adds to the bike.
I have a couple of B17s that I gave up years ago trying to keep in perfect condition. I just drilled, laced and rode them when wet. They survived alright but are both well sagged.
On the other hand I also have a Swift which is like sitting on a rock after 1000’s of miles in all conditions.
All three have been removed and put in the ‘might use in the future’ box in the garage.
I would also agree that my Roberts is nicer to ride on a clubrun or commute with a 200g rather than 500g saddle. Maybe that’s psychological though.
