One of my buddies told me that Sunseeker works best on real sound, zipper fronted cows. I wouldn't want our Sunseeker calf to be any straighter than he is & that calf's dam is a super sound cow. I think that Sunseeker would work on your heifer with the exception being that she may be too straight in the front end for Sunseeker. But, it's hard to tell from a picture, especially with her standing in the straw. Also, Sunseeker is a TH carrier, so you would need to make sure that heifer is clean.
I would think about Dr Who.
