All of these projects just leave so many maybes.
Selling 66% hets just feels so dirty to me. With the leopard geckos I bred in the past, I would sell possible hets at normal prices because there was no way to tell without breeding them out. Sure I would say what the parents were and that maybe there was a chance at a het. Then it would be up to them.
I would personally start with the pied male from #1 and the female from #2. Then at least you can work towards getting some more visuals to mix in on the next gen.
