What's your budget? There are so many __ Het pieds it's hard to pick one for you with out knowing your budget.
If you budget iswhat I would say)
Less than 1k: mojave het pied, spider het pied, cinn het pied,
If your willing to spend more than 1k I would get a visual morph pied male, no poss hets in you pairings, it will jump start your project. You could produce a lot off different stuff if your female proves out.
I'm in the same boat(just opposite) I have a male pied and trying to find something good to pair him with in the future to jump start my breeding projects.
