I have never had anything to do with them, interesting though
yepFather tried some years ago, he says best to stick to one or the other, problems he found was you get the gestation of a lim and the muscle of a blue which relates to a bad calving, but i supose it depends on what way the bull might throw, on lim x bb heifers id be more inclined to a pure lim, maybe a bb as second/3rd calvers
