Betty the sib has shown signs of teeth, and may work well with something like Larry's Obsession, Mort Morss, and Cosmic Sensation. If you are going to work with the toothy ones you can also check out Karol Emmerich she uses some of the dark colors for her toothy ones.
Different photo of the sib – I still have some of this seedling.

Juli – I don’t hybridize for the bi-tones, they are happy accidents. I think most hybridizers (though they like to think they control those 22 or 44 chromosomes) get their best seedlings from “happy accidents” .
Two of my favorite bi-tones seedlings.
ROSES AND SNOW X LESLIE RENEE
TET LAVENDER BLUE BABY X FREEBIRD
Shirlee – Good observation ‘that was my thought of the cross the seedlings show a wide diversity, something some crosses fail to produce.
Michele – The HP X BBP seedling was a surprise I will test the eye on that seedling to see if it will hold, or give up the eye for future crosses.
