My wife tried a Specialized Saddle, among MANY other saddles. She couldn't figure out how all the shims worked and sent it back. Eventually, she settled on a Barefoot treeless saddle and has been very happy with it for years. I actually bought a Barefoot saddle for my barrel-shaped KMSH that I ride only occasionally.
Nothing wrong with the quality of the Specialized Saddles. And, you may figure out the shim system and be very well satisfied with it!
