How many calves has she had?
Heat Seeker could be interesting, Heat Wave Son or Clone, Who would make some nice females. What do you want out of her would be my question? Do you plan on keeping her heifer? I like the idea of Sunseeker as well. She is clean enough that he might stouten her calf up a bit. Very feminine gal.
Macho would make some nice replacement females. I really like my Macho heifer. Besides being great cows our experience is they have a great tempermant.
