Actually, my first leather saddle. I had been reading such good things about them on these forums, that I just had to try it out. I picked up black B17 on Amazon for $101. Just took delivery of it this evening, and applied it's first coat of Proofide. It's already mounted on my hybrid (Trek FX 7.5), but I haven't had a chance to try it out yet.
It's much more firm that I was expecting, and I'm sure the first few months won't really be all that pleasant. I've been using the Serfas RX saddle for about a year and a half, and really like it, but have been wanting to try a leather saddle for quite some time now.
I'm hoping that being a clyde (265lb) will help speed up the break-in process.
