The Avatar Gel 143mm on my Specialized Roubaix isn't cutting it. The only thing I can't get right. The LBS has limited stuff. Can anyone recommend a place I can buy a saddle and return it if not satisfied (of course assuming I don't soil it). I am looking at the Selle with the cutouts as I have a prostate issue and need to avoid pressure there. The issue with the Avatar is that it feels like I'm sitting on a "shelf", but going smaller for a ride in that saddle still became uncomfortable.
