I had a Brooks that I rode hundreds of agonising, tear-inducing miles in the promise that it would be 'Just a bit more' before it broke in.
It nearly put me off cycling completely, till I got rid of the thing and bought a Madison G12 gel with a lycra cover.
I did have a Lepper that came on my first Carlton. That was OK, but it was so old, it just fell apart within a couple of months of buying it.
I have a Lycett from my Rudge, but I am reluctant to try it. For the sake of verisimilitude, I have fitted the Rudge with a Brooks saddle
