we have one polled and one horned . I never thought of it before but the horned bull is a little more aggressive with the cows maybe just by chance . I like the horned herefords better than the polled just seem a little framier . if your using true angus cows with out any simmy or something that might have a reseve horn gene i'd go with horned but have your breeder knock them off at least get shorter than the ears   never can be to careful.
