Noone's going to able to give you more than a good guess on this question. You'll have to decide if you can breed him to heifers and live with how it works. Some have used Witch Doctor and gotten along OK and some have had some difficulties with him. You should be able to get some fairly accurate #s on Saugahatchee.
Saugahatchee is good on bw's for sure. His influence should add a lot of eye appeal to any heifer calves you get. My favorite angus heifers have allways been Saug's. Good luck with breeding!
