I think as seat tubes get steeper, stubbier saddles like the Spec Power make more and more sense due to needing to shift fore/aft less depending on incline. That said, what is the closest saddle to the Spec Power that's not Specialized, I have access to most via shop deal.

I've been an Ergon fan for years but admittedly running the Enduro Pro Ti, it may be too firm. I'm running the Med and keep meaning to ask the rep to try the Small to see if it feels better.
