I was a member of the Cornish Rex Society (breed club) and there was a discussion regarding Sphynx and C Rex when the Sphynx first came out. I know of a Devon breeder that was using the Devons with Sphynx, but apparently they found it was not working well and so stopped the Devon/Sphynx breedings at some point.
The Cornish breeders would not allow their cats to be used with the Sphynx cause they did not want the bald gene in the lines.
