This OC seems a little more efficient. True confession. I don't have the experience of OC's being aggressive just because they're an OC. I have some mild OC's. I find both of these C plates to be on the mild side but so smooth I can do 4 passes without leaving myself with lobster face. I can go ATG with both on the bottom band of my neck. That's unusual for me. I like them a lot.Very nice!! How's the shave with it compared to your plate C SB? Any difference?
