While I'm under no illusions that anyone cares about this any more, I did want to close out this thread with my final-final saddle choices after a couple of months of fiddling around. This all started because my Selle An-Atomica (on my Davidson) needed replacement and my Brooks Swift (on my Tommasini) didn't like me.

Final disposition:

- I purchased a Selle San Marco Regale, which I found via this kit, for my Tommasini. So far, I've had it on a couple of 50+ mile rides, and really like it. I sold the Brooks Swift on eBay, which more than covered the cost of the new saddle.

- I sent my Selle An-Atomica off to get re-covered and refurbished; I got it back a couple of weeks ago and it's doing great. Still my most comfortable long-distance saddle.

- My commuter bike, the Boedie, still has a Brooks B-17, and is doing fine.

I also brought a Brooks Professional out of semi-retirement while I was doing all of this testing and re-discovered how much I like that saddle. It's on a backup bike for now but I will make sure I hang onto it (it's almost 30 years old now, still going strong).

So my lesson here, 25+ years after I bought my first Brooks, is that non-padded, smooth-shell leather saddles is what I like -- Brooks, Selle San Marco, Selle An-Atomica. The one thing in common, for me, is the almost complete lack of padding to make a saddle comfortable to me. The WTB saddle that I liked is the only saddle here w/padding that worked at all for me, but still ended up not working as well as the San Marco Regale. But, as I learned, that's just me -- this kit overall taught me there's no way I would know what works for me unless I try it.

BTW, someone on another forum mentioned that this demo kit is no longer being featured by Competitive Cyclist -- the link on the website still seems to work, but I'm not 100% certain this is still something they do.
