Old School has been my 1st service bull of choice on heifers for the past 3 or 4 years. I haven't had any monsters, but they don't necessarily come like mice either. BW seemed to be pretty variable, and depend a lot on gestation length. I'd guess they ranged from 65 lbs. up to 80 lbs., w/ 1/2 of them needing assistance. Quality as they grow out is just ok. They aren't dinks but I didn't have one I felt was worth marketing as a show steer. I think I've retained 1 female as a replacement. On the plus side, they seem to be a little harrier than other Angus bulls I've used.
