I have two corbins. After riding to Key West on Prudence with Vera's corbin, I decided to remove Vera's corbin from Prudence and use Cinnamon Girl's corbin on Prudence for the ride to Montana last month.
Both corbins are the hard type. Vera's rides harder than Cinnamon Girl's for some reason.
What you have is a hard saddle. Will it break in? No. But your buttocks will. That said, the leather will shift to match your back side. Just a smidgen though. The beautify of a hard saddle is the lack of hot spots, the fact that it allows one to sit in the bike instead of being perched on top such as the oem saddle placement is.
