Looks to me like you have a pretty nice heifer, if you really want to get the best of both worlds breed her to a horned bull. Maybe, Churchill Sensation 028X, the cross between the polled and horned genetics give you a little extra performance. The horned cattle were always superior to the polled because they polled were selected for so long mainly due to the only breeding criteria was that they were polled. I will say that the polled cattle have become very good in the past decade and I use them on my horned cattle every year and horned back on my polled cows. I like the results of the breeding and I believe that the offspring show the results. Good luck and I don't think you could go wrong with any of the bull that have been suggested.
