I have a couple of upcoming daughters of this guy
Haven't used him yet, but I like a few weaning age daughters I have seen
A couple daughters (just 2 year olds now) are doing a nice job
Have a few heifer calves on the ground showing some promise by this old guy
Have bred cows for the second year to this grandson of Substantial and I like the heifer and bull calves a lot
And finally after a test run last year, I am looking forward to the daughters of this bull dropping calves in a couple years -- will be watching feet on them
Several of these are pretty young bulls, so I am proceeding with caution on them. I make a few mistakes as I go, but we can always eat the mistakes.
Quite a few of my current best cows are sired by a home-raised son of BC Lookout 6024. His mother was a granddaughter of EXT. That doesn't help much on looking for current AI sires, but they are rising to the top as they hit their prime even if they have a few faults. Also Redland Emblazon 2134 is the sire of some other top cows here. Unfortunately, 2134, like some other sires aren't available as AI sires by the time we figure out how good they were.
Another bull I like for a maternal AI sire is KCF Bennett Absolute.
http://bullbarn.com/angblkepd.asp?ID=2379 He is a little more proven and I like the Wulffs EXT 6106 on the maternal side.
SAV Resource is one I resisted using for several years, but a couple of 2-year olds are showing promise this year.
Hoover Dam is still available and has been a strong maternal sire.
