One and Only is doing a fine job of breeding and as a Free TH Heat Wave son he definetly has a place. But as a heifer bull, that is not his place!! We have a neighbor with low EPD angus and they have had a couple of One and Onlys out of heifers and have gotten along great,, they had no issues but the calves were about as much as you would want out of a heifer. We have had no issues with him on cows, and this is our second set of calves and plan on a third. On clean cows the birth wts. have been pretty moderate, but on carrier cows (both TH and PHA) the calves can get up into the upper 90's,,we have only pulled one calf out of him and that one was backwards. One and Only is a good bull and should be around for some time, he is by no means a cow killer but I personal would not use him on heifers, especially any clubbie type one.
This is how I see it and I know others will say he is OK on heifers,,,use your head on how you breed to him. FYI I plan to put up a pic of a One and Only heifer on our profile pic,,SHE IS SEXY!!!
