I'd suggest that whatever you breed him to(mojo, mystic, or normals, IMO), keep it small so that you can hold back ALL the offspring if necessary.

I'm kinda in the same boat, as I have a CH male that I'm confident will prove out, but don't want to extend myself beyond my own capabilities of keeping offspring from him. I'm going to start off simple with a couple normals and a pastel to try for a combo...maybe a cinny too.
