Carmina offers the same black captoe in both calf and shell cordovan -- I'm interested in the shoe, but I'm not sure which one I want. I feel like I haven't seen many black captoes on this forum is shell cordovan. Is that because it's a style and/or color of shoe that is not often made with shell? I've never owned a shell shoe, so I'm admittedly ignorant on this subject (i.e., any guidance or advice would be appreciated). The price difference is about $200, which isn't a big decision criteria for me, but thought I'd mention it. If you were me and deciding between the two options, which would you choose? Thank you.
