i got a alli blue roan cow that has NOO depth or muscle whatsoever, but shes super feminine and strong topped. but she throws massively thick calves. still no depth, bred her I AM LEGEND last yr, calf is stout, smooth, and actually as deep as any of my other calves. i personally like i am legend, ive seen some good calves outta him, he just never got as much publicity as he should have. i would personally go i am legend, thriller, or other heat wave genetics, or eye candy. post a pic of her and her offspring if you can or got any. it may help.
