If you use All About You make sure your female has extremely good front legs and is very sound. I've seen some real train wrecks on some cows here locally. Several local breeders have used him quite a bit and although, in general, the calves were extremely stylish and showy looking(especially at 5-6 months of age)they also generally seemed to have poor confirmation--particularly in front and as they got some age on them. These are just my local observations, but we've had AAY calves win our prospect shows and then not be sound enough to show as older calves.
As I said, these are just my observations, but maybe enough reason to do some more research before using him!!
