I'm thinking about switching back to flats and need some new hoof covers.

Can anyone tell me if the am40's are stiffer than the impacts?

Do any of the impacts have differing stiffness? Karvers?

Damn I never found my last pair of regular Impacts stiff enough, I was hoping that Shimano used the mp66 mid with a sticky sole. Are the Karvers any stiffer?
