Sounds like a great cross.
I couldnt see Penny Black on the list.
I am also interested in the Black Domina's medical use. I'll be getting a straight BD so will compare the differences and see their usefulness for RLS and insomnia (Which I suffer from )
Ryu's ak cross was like candy for the head...big respect!!
Last time I ad straight domina it murkled me!
I'l second that!
