First, I have yet to calve one from either bull.... I probably should be quiet, but here it goes anyway....I have seen Tyson @ Cores and Hawkeye Breeders a few times. Good bull, moderate in size, very sound in my opinion. The calves I have seen have the clubby shape, nice calves especially heifers. I have seen Dirty Hairy @ Nichols and really liked the bull, he also looked sound but maybe slightly taller than Tyson (They were 20 miles apart so take that with a grain of salt). I haven't seen too many calves, but he seems VERY popular and there are lots of pictured calves on the internet. I hopefully with have a calf or two by each this year....
