Interesting idea. I looked at the pics of the HS Wild Cat and found one from OrchidRoot below that is stunning.

Now, I rarely like any hybrids and this one calls to my curiosity (much like how Rolfei peeked my interest back to paphs).
Perhaps I can use the leucochilum 'Blackest Knight' pollen on it if there is a majority support from the members here who are willing to grow them out as an experiment, I might just take the plunge?
Any takers?
If the identity of the WBW is confirmed and you can get them to the US I would happily grow some out.
I wouldn't sweat the petal length too much since the form of the flower is so different from a standard WBW, and the 2cm petal width is huge. I would look at roth-y shaped Hilo Black Eagles as a more apt comparison for award potential.
