Well, just to update folks. After reading the threads here, I decided to try out a Brooks B17 from Wallbike. I've had it a week now, and after making a couple adjustments, I find it quite comfortable, and I haven't yet tried it out with bike shorts. Today, I did about 20 miles, my longest ride so far. I can't imagine how it will feel after I get it broken in. I know I need to find out how it feels in the 50+ miles range, but for now I feel like one of the lucky ones: found my saddle!
