I choose chisum. Mainly because I have had many calves out of him, and have been impressed with each one. Bulls and heifers. I have 3 herd bulls I have saved for personal use. They have turned out great. The temperament of them is unreal to me, tame as a dog. (Not always a good thing I cuss them every time I load them in a trailer) I looked at chisums numbers and it looks they dropped his carcass numbers quite a bit. I didn't breed him to any last year, curiosity gets the best of me always wanting to try new bulls. I have no experience with charlo whatsoever. Pictures and video I saw he looks awful nice.
