The bull (6I6) was noted/liked for the docility he tended to sire in his daughters.
Was not liked by all Angus breeders - some called him "ol' banana balls", and one local breeder told me, "be nice, we're trying to breed bulls with high scrotal score, why would I want to use something that's gonna shrink 'em?!" Though, I did have one veterinarian suggest that LONG testicles, like 6I6 sired, might have more sperm producing tissue than they were given credit for, merely based on the routine circumferential measurement.
