I fit well on saddles that are pretty flat side to side. Rounder saddles like the Prologo Scratch or San Marco Regal cause me sit bone pain very quickly. I was riding a Fizik Antares VS but wanted something with a narrower nose and a bit of front-to-back curve. The 134mm wide Nago Evo fit the bill and the "Hard Black" color looks great on the bike. After 150 miles on it I don't think about the saddle at all when riding - it's totally comfortable and there's no pain or numbness associated with it. The construction quality of the Prologo is top notch, and I expect to get many thousands of miles out of it.
