I saw this when you posted it and it triggered an incomplete memory. So I had to cogitate over it for a while to remember what I've heard about high tail heads.
I hung around with a guy quite a while ago that made his living inseminating cows. One day he was inseminating a Brown Swiss I'd brought home as an experiment, and he mentioned that the breed tended to have high tail heads... and some problems from them. He told me that the high set allows contaminants to enter the vagina on the females, causing breeding issues. So not a problem with bulls/steers... but a potential issue with cows/heifers.
In a terminal circumstance where all calves are going to slaughter, no problem. Otherwise, be advised... for what it's worth.
I like the bull... but I trust the guy I hung around with. He'd had plenty of experience breeding cows.
