Rendition will add more power than Built Right, Built Right makes some nice females but they are feminine. I have no problem using Dream On, and have seen some nice angus x Dream on cows. Jeff Miller just had one in his online sale that was a dream on x angus, and she was heavy boned and full of power. She sold well, and I saw her on the trailer when my heifer was delivered and she was the real deal. But, if the cow does not have enough power, Dream On might not be the best choice. No Home Boy offspring are out there yet that I know of. So I can not recommend there.
Are you really stuck on white face? Beef Maker, and ABS bull, really adds some power to his calves. And he is heifer safe. I have seen a few of his calves, and reports coming in are really good. But no white on his face. He also has a real good set of EPD's.
We have a red bull with a white face, but he is just a fall so another year before he can be used. Really good looking bull, and was an embryo calf sired by Built Right (we had a black with white face bull from the same flush that we raised and sold in Spring, did really well with him).
I think Chopper is hetero, but not positive. He is really putting some nice calves out there.
Hope that helped some! I just love our simm x angus crosses, and the red angus x simm crosses are gaining a ton of popularity. They grow quick and make fantastic mothers.
