I only have two chisum calves and I'm very happy with both, one heifer and one bull calf, about 9 months old. I've got 4 Investment calves. I couldn't be happier with the bull calf, the three heifers were looking good on pasture but now seem like they've lost some growth momentum. I had 4 Priority calves. Two bull calves were nice, not awesome. One bull calf never did impress much, and one heifer that looks real nice. My SAV calves also are deep but leave you thinking they should have a bit more height to them. Maybe that's a SAV thing, squatty short animals?
I'd use chisum again, probably Priority. I have 10 coming heifers coming with Investment again, if last years heifer calves don't kick it in the rear, I don't know that I'd use him again other then for a fail safe heifer bull/calving ease.
