I don't know the color genetics of color yield, there are different ways to make white. One way you will get white chicks, the other they can be about anything but with a BA you will probably get black. There is only one way to find out.
What is stopping you from doing both, rangers and color yield with the BA? That way you see which you like best. Worst comes to worst you can eat your mistakes. Successes too.
