Does anyone have experience with a W.Leghorn/B.Orpington cross?

I've had some Buff Orpington rooster X White Leghorn chicks. The offspring were primarily white and they were in between both parent breeds in both temperament and laying ability; pretty calm and docile birds, probably closer to the Orpingtons than to the more high strung Leghorns; and excellent layers, not quite as good as the Leghorn hens, but better than the Orpington hens. Their eggs had a slight tint to them, sort of a cream or light beige color.
