Personally, Who Made Who on pb Angus cows hasn't worked very well for us, our best Who's are out of Maine or Simmi influence cows. I could see Naughty Pine working well on Angus cows. Meyer Meyer could work on stouter Angus cows for females, my thoughts are to try him on some more "souped up" type cows, though. Alias works on Angus cows pretty well from what I've seen.
