he is a super calving ease bull and has a good carcass to boot, so you should sleep well at night. as far as performance, muscling, phenotype, etc., I do not know.
9150 sires small bone cattle that don't flesh. I would group him with dairy cattle on phenotype. I used him on cows and heifers and the majority of his calves were not beef type. On the plus side you will not have calving problems when using this bull.
