Salers. Amazing how one cow can sour you towards a whole breed. She and a few other difficult cows actually came with this farm when we purchased it. Told the old man that he'd left a few and he said good luck with them. That's been around 12 years ago and she's the last of those original...
Reminded me of when I first got started and had my bull pulled to synch the cows. Called the neighbor and complained that his bull had gotten in and was breeding my cows.. he listened to my gripes and then said, "well, your welcome". 😆
I'd suggest splitting the difference and using an all around balanced bull that you could retain feminine heifers from and will also sire good steers.
Unless you're considering some entire breeds, like continental, as terminal(?).
