Pieds is a great project! As of right now i have a visual male and het female(she waiting breed). The reason i got the visual male is i can make 100% hets every time i pair him with any female. I have began the process of stufing him out to some friends codoms and taking pick of clutch when they hatch(getting my future co dom hets for free basicly). I also have plans to buy a visual female, because if all else fails i can make 100% pieds from pairing the two. Next on the list will be a coral glow male(just because i love coral glow pieds ;-) ). All recessive projects are a pain, but in my opinion the most rewarding.

I would avoid the het trio. You only have a 25% chance per egg of creating a visual, and on top of that any hets you create will.only be 50% hets. Making them incredibly hard to sell and prove out.

Best of luck with your pied project :-) who know if you have sucess, i may end up being a customer one day LOL
