Most of my founding females are CH females, represented as such when I purchased them, and not "specials" other than being reduced patterns, which I love. I'd say that most of the "big guys" all have CH animals in their collections, and I know several others who do add unique females from the yearly CH's.
My personal line is not to deal with anyone who deals in WC's. However, if Neil Golli, for example, had a nice CH import that would fit into my collection, I wouldn't hesitate to add them to my collection. I even got a nice CH from EbN two years ago. She's now in Frankykeno's collection, as I gifted her to her after she lost an animal that died in her hands.
If a CH is acurately represented, fairly priced, well started and the seller is in good standing, I have no problem with CH babies.
