The chips where from @liftapint. Cards from a great guy named Mike, found off forum. I can PM you his email.
I don’t have HSI chips, so I haven’t looked for those cards. For Cincinnati and Cleveland, I have found plastic KEM or KEM type for both casinos. They’re both bridge. My Cleveland have jumbo but the Cincinnati are regular. For a while you could find them on Amazon.
For poker sized, I have Cleveland plastic coated paper. They do have jumbo.
So that’s what I know about horseshoe cards. Maybe someone who knows about HSI can chime in. Good luck!
