That isn't the route I'd go for 10-20 mile rides. When I started back riding 5 or 6 years ago, I had lots of seat fitting issues, between sitbone blistering issues to taint pain. I've read a number of stories from people that had issues when the leather got soaked...you need to keep the leather properly conditioned, and people recommend wrapping it with a plastic bag in the rain...seems too maintenance intensive for me. People DO say they're comfortable, though. I imagine with our FL heat and humidity that I would ruin one with sweat pretty quickly.
I did the simple sitbone width test with some cardboard and figured out I needed to start with a wider seat. My sitbone width was out at the edge of my 155ish seat, where it was turning down.
Once I figured that out, it took a few seats, each one getting better, and I've ended up with an Ergon that I'm really happy with. I don't start getting any discomfort from it until 2.5 hrs, and then it's just some discomfort. If I lose the weight I need to, the issue would probably disappear.
I bought a Brooks C17 to try to get the Brooks comfort with the weather proofness. I bought it for a new build that I put together while healing from a AC (shoulder) tear. I hadn't ridden bikes for a couple months and probably shouldn't have jumped right on that new untested seat with my now-soft butt. 35 mile ride and I had quarter-sized blisters at my sitbone spots. Had trouble sitting for over a week. I may try it again one of these days.
One of our bike shops has a set of WTB loaner seats that they let me try out for a week each (though only two were wider, I think).
