I would think this would be of interest to the show type person that knows the bottom side. Just on my knowledge of chocolates it is a Different old influx of Chocolate blood (bottom side) As for Ryder there was very limited semen available on blue Ryder, he had pretty limited breeds to both show type stock and FC type stock as he had the unfortunate issue of being chocolate

. There were some straws available on Cuda, but that was 15 yrs ago when I searched so who knows now. In any case for the limited breeding on these lines even the show crosses have produced some of the most noteworthy field chocolates FC AFC GRHRCH MNH upper Pointing titles etc. and even a few blacks of this generation, even a few CH if I remember correctly. I'm not familar with this bottom side but just thinking legacy associated with dogs like Cuda Blue Ryder, Pirate, Roux, Drake, Buddy, Preacher, Mastro. For $1800 having something like this to breed back to might be worthwhile, if someone was looking into adding diversity to tyically heavily inbred chocolate lines.
