I think Midas is one of most fault free bulls (not necessarily show ring) but Cunia has had the most impact. PC Metric 707 is a bull that I feel would be interesting to go back and sample because he had a great mother and you see him in a lot of pedigrees including Irish Whiskey and Draft Pick to name a few.
I'm not nominating Draft Pick for the brackets, but I can sure say he was revolutionary to the Maine breed. If it wasn't for him, we may not be required to genetic test our Maine's for PHA.
My nominations are:
Cunia
Power Plant
Polled Pursuit (I'm not a fan, but he did have a huge influence)
Strutt
Ali ( Again, not a huge fan, but a huge influence)
Hardcore
