I ride a hybrid bicycle 400 miles per month on city streets and bicycle trails. The Brooks B17 provides an excellent balance of comfort, weight and rigidity for my style of riding, and requires - in my case - no break-in period. I enthusiastically recommend the Brooks B17 saddle to other riders.
I just got the Trek Domane endurance bike. On weekends, I like to go on long hilly rides on remote roads that are bumpy and not consistently maintained. I'm the opposite of clydesdale, I'm 5 7, 130 lbs with fairly narrow sit bones. Prior to purchasing this saddle, I tried the Arione Classic, Sella Italia Flite, and the Brooks C17 and the Fabric Scoop Shallow version. The most comfortable one surprisingly was the C17 but I just couldn't stand the look of the C17 so I took a chance on the Scoop Radius model. The longest ride I've been on w this saddle is 81 miles w 5,500' of climbing. Initially, I thought the shallow model would the bill but it felt a tad wide and I could feel the edges on my inner thighs. The Radius model slopes down more like the Brooks C17 so perhaps that's why it feels more comfortable to me. The Radius model seems squishier than my other saddles but have not bothered me any more than my other saddles. The curved top provides a secure feeling on long climbs unlike dead flat top saddles like the Arione. One downside of the saddle is that it's a little difficult to keep clean. Because of the rubber like material it tends to absorb dirt, smudges and grease much easier than other saddle materials. For the money however, you can't beat the saddle. It's sensibly constructed, comfy enough and looks decent, all major boxes checked, I highly recommend it. The trick is to figure out which shape (flat, shallow, radius) will work best for your needs.
