All my cows that I bred to him to we're 2nd to 5th calvers and I did not have one weigh more than 84 lbs (bull calf). The lightest was a 68 lb heifer. Now none of those were clubby bred. All Angus cross cows. He's made me a believer for sure.
If I remember correctly a friend of mine bought some from this guy. I have never dealt with him though. It says its $25 a straw on his website.

I know around here the show supplier usually has used blowers for sale. They have rebuilt them or at least checked them over, just something to think about. But def would invest in one.
I can't help you out as Dow where to keep your steer, but I would suggest not looking for a certain breed. Look for the best bang for your buck. Good luck
