I am not familiar with that site or name on the site myself.
One thing that the hybridizers have said about choosing among seedlings for a hosta as a breeder, is to choose one where ALL of the leaves have streaks, because otherwise it will revert. I think that may be another thing to watch for when choosing a plant for my garden when I want a streaker.
I have seen Lakeside Mom, Fickle Blue Jeans, and Zing Zang mentioned as being used for hybridizing by some people. They could be fairly stable. I do want Fickle Blue Jeans myself.
