Brooks threads can be about the most opinionated. I have bought three new in the last 6 or so years. My conclusion is that like everything, brooks are not for everyone. Comfortable right out of the box, but for me, they look like the OP's pics within 200 miles, and within a year two had hit the limit of adjustment despite always being covered and treated, and the third actually split at the nose before hitting the end of the threads. Threads were only tightened when the leather was about hitting the post.
And before everyone chimes in with the "you did not do it right" its only the newer brooks that have done this. The two saddles that I bought before the resurgence of their popularity are very broken in, but at 15 to 20 years old are only about 1/2 way to the end of their tension threads. Luckily I have some tack experience, and have stretched new thicker elk hide leather on my old rails, and the rails of several brooks that friends were throwing away.

I mostly agree with the statements in post 20. The refutations in post 21 are all fine and good, but are just as based on personal opinion as any argument for or against can get.

In the last few years all my tours have been on synthetic saddles. Old Vettas, Selle Italias, and Avocets that are at least 25 years old when I got them have lasted longer than any leather saddle purchased recently. Again, thats personal, I might have gotten lemons or else the recent tanning techniques used don't work well with my sweat. Fortunately a certain Oval concepts saddle fits me like nothing else I have ever ridden, they are cheap, and I discovered them in a take off bin while replacing the flyer with the split leather nose.
