I'll start off by saying I think your 11-year-old had a pretty decent eye! I like this bull in the photo, but that's about all I can speak of on him. I'm not familiar with that pedigree, and I haven't heard of the bull before. I looked online and couldn't find a video of him anywhere, although he doesn't LOOK like he has too much set in the photo. I know sometimes a photo doesn't exactly represent cattle as they are, so I'll just have to take your word on that. As far as soundness and structure, I would just say I'd rather cows have a little more set than they need than not enough. A straight legged one won't last as long.
I raise Simmental and SimAngus cattle, and we're AIing some Angus females to Angus bulls as well. I'm basically responsible for the matings on about 100 cows a year. We raise seed stock cattle with commercial appeal...the birth weights on the bull calves have to be acceptable for commercial cattlemen, the calves need to have some performance and growth, and they have to be sound and functional with some eye appeal. We're not trying to raise show cattle...we raise breeding cattle. A few of them do get shown, but that's not our primary target. We market primarily through an annual production sale and private treaty sales off the farm, and we've been in the seed stock cattle business since 1971.
Thought I'd share a few names of some Angus bulls we're either using or have considered...there are a bunch of em out there! I do use some Simmental and SimAngus bulls in addition, and I like the Simmental x Angus cross a LOT, but I'll keep this list focused on the purebred Angus bulls...
The bulls I chose this past fall were Connealy Consensus 7229, Connealy Right Answer 746, Yon Future Focus T219, and EXAR Upshot. These bulls seemed to put together the phenotype, pedigree, and EPDs that worked the best for me right now. The Right Answer bull was used exclusively on virgin heifers. Consensus and Future Focus would be the first two I would recommend to somebody in your situation. Those two might be the ones I'm most excited about. I've seen some Future Focus daughters at Yon's in South Carolina, and they're pretty nice. He'll make em real deep and cowy, moderate enough in frame with plenty of growth, and sound legged. The bulls at Yon's last fall sold VERY well with one son going to ABS for $20,000. I have one purebred bull calf on the ground and a handful of Simmental cows bred to him. I haven't actually seen any Consensus calves, but I've seen a bunch of photos of calves I really like, and that bull seems really hot right now. I used him on both Simmental and Angus cows.
I bought a GDAR Game Day heifer last year that has a really nice heifer calf by Benfield Substance. I don't know that I would have picked that bull out on my own, but I really like this heifer calf a lot. A few other bulls I've either sampled or considered using are SydGen Mandate, S S Fast Track, Connealy In Focus 4925, S Chisum, 6175, S A V Pioneer, and Quakerhill Objective 3J15. We had a couple of nice SimAngus heifers out of 3J15 and some real nice SimAngus bulls sired by Pioneer. I just have one Fast Track baby on the ground now, and it's a little early to tell much about her, but she seems to be doing well. Haven't actually used Mandate, 4925, or Chisum, but there are some things I sure like about those bulls. I do have a yearling heifer sired by Mandate, and I think she'll make a nice cow.
There are several Angus bulls I'm trying to keep on my radar, and the list seems to keep growing. I do look at EPDs pretty closely, and a lot of bulls I might like otherwise tend to sort themselves when I bring in the EPD package. Even if it's one or two numbers that stick out, that's enough to keep a bull from getting used in our program. But we don't JUST look at EPDs...that's the fastest way to have a train wreck in my opinion! Find the bulls you like first, then sort them on paper. If they aren't good on the hoof, the EPDs are completely useless.
Lastly, I'll just mention this... Every breeder looks at calving ease and birth weight and growth and maternal. The real cattlemen I try to learn from pay a lot of attention to some numbers that not everybody even considers... Don't ignore a Maternal Calving Ease EPD or a Scrotal EPD, and I've learned to watch the Docility number as well. EPDs can be a little overwhelming, and I know not everybody believes in them, but they're a pretty good tool if you know how to use em.
Tell your son good luck! The only thing more exciting than choosing a mating is seeing that baby hit the ground!
