Very limited experience, only 2 so far, but here is are my thoughts after only 2 calves out of 2 first calf heifers that are both OCC Freestyle heifers. 1st heifer had a heifer calf unassisted approx 70 lbs. Just got back in from pulling the 2nd one, bull calf approx. 90 lbs. Looks like you will get along OK if you watch closely and don't mind pulling some. I don't think that it looks like you should ever have to do too many C-sections unless malpresented. The calves are nice shaped for calving IMO. I cked into the bull fairly well B4 I bred to heifers. De Jong's, Willers,Myron Danner, Majors, & of coarse CTR,(Eldon Star), have all used him on many heifers with success.
