Ohhh I love black smoke as well!! They are not that rare to find, and one day I hope to own my own black smoke maine coon.
It's one of my favourite colours in Maine Coons, next to blue (tabby), black (tabby) and white. I know someone with a black smoke tortie with white Maine Coon and that coonie is absolutely gorgeous! So maybe that would be an option as well for the future, but with torties my problem usually is that I find it more difficult to find one to my liking...
