I LOVE my Brooks My Surly came with a B17S - was too short. I changed the saddle to a regular B17 the night before a 40 mile ride. Had to stop and make a couple of adjustments, but it's been great ever since I just put a flyer (B17 with springs) on the back of our new tandem - comfy from the start. So yeah - I'm in the brooks camp (and I probably won't replace my Butterfly saddles when they wear out - I'll just buy Brooks saddles for those bikes too!).
