I went to my LBS this morning. They had a couple of versions of the Planet Bike ARS saddle in stock to show me. Besides that, they told me that if I wanted the ultimate in comfort and durability, I could go with a Brooks saddle. They didn't have any Brooks saddles in stock, but they had one installed on a bike they had for sale, and they showed that one to me. Don't know which Brooks it was.

I decided to buy the wider of the two Planet Bike saddles. I watched as the salesperson installed the new saddle, and asked about how it's done. He told me that all I'd need is an Allen wrench, so I picked one up while I was there. It didn't look like it would be hard to learn, or do.

I haven't yet ridden my bike with the Planet Bike saddle, but I will today (if the expected rain holds off) or tomorrow. I sat on the new saddle, and it does feel more supportive. If I like it, so much the better. If not, I can look into a Brooks or something else.
