Why did I totally misinterpret the thread title? Am I conditioned to read 'the usual stuff'? Sorry
Anyway, I've had no end of saddle and seat pin woes. Once, years ago, the seat pin snapped off close to the seat tube. I felt it going and was able to save my manhood!
Asked at the bike shop, they said the only way to get the broken bit out, was to hacksaw it from the inside, running a blade up and down. But it was immovably welded to the frame (alloy in a steel frame, you see - and not properly greased!
) I ended up scrapping the whole frame. And it was my first hand-built 531!
And more recent trouble with a single-screw seat post that just
wouldn't grip the saddle, tighten it as I may. Eventually when I switched to a two-screw post, that solved that little problem. I would advise, especially if you're on the - er -
bulkier side, avoid single-screw posts in which the screw comes up through the middle of the clamp.
And another time with a Brooks, I broke just about everything in turn. First the rails, both of them snapped simultaneously. Another time, the U-bolt at the nose end, snapped. Titanium: I replaced it with a steel one from another saddle, and it was OK after that. And the leather. You're supposed to stretch it just
that much, but not
too much - very difficult to get it just right. So I must have overtightened one, just too much, and the leather parted company at the nose end. Despite diligence with the Proofide. End of that saddle!
I'm not over-enamoured of Brooks now, as you see! Next time I have to change a saddle (my present Brooks is OK btw), I'll probably switch to something else.
I fancied the extra training 
. But because we where young, it was cooler to ride with the saddle low rather than at the right hight, so i'm quite used to cycling a few miles whilst standing, not very fast mind.
