I've been thinking about the rubber SA, my experience with the rubber brooks wasn't great so I dunno why I'd try again with another brand, but I've been doing alright on my specialized toupe at 155mm, but they've discontinued them it seems and I haven't had any luck on ebay or pinkbike lately... and they aren't the most durable saddles either, I've had the shell crack on one, and snapped a titanium rail on another.
