Breeding ISA brown rooster to...?

[FeatherQueen3]

So, I have an accidental ISA brown roo. I also have an accidental exchequer leghorn (or mottled ancona idk) roo. I'm thinking I'm going to keep the ISA brown. I don't have a recent pic of him on hand but he is solid white with just a few brown specks at the ends of his wings. Are there any cool combos I could make with him that either:
a. are great layers; or
b. are aesthetically pleasing

Some hens I have are: Various polish, MMM Marans, Blue Splash Marans, various Cochins, Light Brahma, EE, Green Queens, Splash Ameraucana, Welsummer, Speckled Sussex, Swedish Flower, Egyptian Fayouomi, BLR Wyandotte, Gold and Silver laced Wyandottes, OE, and Meyer's Steele Egger. I do have ISA brown hens and a Golden buff as well.

Has anyone ever used an ISA roo for breeding?

I have never had ISA browns, but I have a mostly white rooster. My roo has passed along white area mixed with colors making some interesting crosses. My birds are so mixed I am long passed being able to predict chick outcomes.

i would reccomend ISA brown with the welsummer or speckld sussex for good/pretty layers
