I can't advise you about those, but will be watching. I love white eggs, b/c they are so much fun to candle when incubating them. My choice, due to my climate would have to have a rose comb. Yes, there are rose combed leghorns. I've had some. They are on the flighty side, I don't mind that. They are not aggressive. They are good layers, but not as good as the singe combed leghorn!
