Your Genex Rep sounds like the rest of the company, they are trying to sell other bulls based on what the company tells them.
Oak Hollow is very small framed, good effecient desert cattle. But if your looking to downsize at least 2 frame scores, no nuts, average heifers he just might be your bull
Front Range i think is a good bull, I have seen some calves out here in the west. They are pretty good. Kesslers run a great program. I actually like his daddy better. Frontman
Quiet Lad has also been used out here in the west, starting to see some calves. I will see some fall yearlings this fall.
As far as Final Answer goes, I would stick with the program and since you can't get him. I would definetly use a son. Pioneer being the best and seen several successful breeding with heifers, calving ease ok. But he is also backordered.
I would suggest if you have to use a Genex bull, Boyd Resume. Genex will tell you to use Connealy Right Answer and he is good, but not my first choice.
I would suggest this bull http://www.universalsemensales.com/detail_angus.php?angus_id=394
McKeller Final Call. Awesome!!!!!!!!!!!!
Remember I don't work for any semen company, I am a registered breeder and have no ownership to these bulls. I see lots of cattle because I carcass ultrasound and AI lots of heifers for folks in the West.
