Bruv, there's like 20 saddle threads on the first couple of pages this board. Quick summary: width (should be wide enough for your sit bones), shape and angle (should be horizontal to a little bit up) are the things that are going to affect your pain or lack thereof. If you're doing longer rides and not wearing bike shorts, you probably want something with a reasonable amount of padding. otherwise there's no real way to tell what's going to do you right, but there's a trade thread (and a saddle only one in 'for sale') if you want to try something new...
