My B67 has the long nose (not an "S"). I use the long nose to help control the bike. (one of the reasons I'm really hesitant to return this seat)
About the only way I'd change seats at this point is to get the B68 when it comes out.
The noise is bugging me less now. Talked to a LBS guy who said the noise is the price you pay for supreme comfort. It's the metal on metal in the shackle, Kit. The springs allow the frame to torque and the shackle at the front is the torque limiter, so it makes noise. I've put more grease in there, and have accepted that it will make noise.
It is really amazing seeing the leather soften and realizing how incredibly lopsided I am.
It is the most comfortable saddle I've ever had. I'll stop whining now. It's worth it.
