IMO there is nothing out there to breed to for simmys. My herd has significant influence of dream on, powerstroke, and meyer. If you go back a ways, everything is either x339u/c339u/black max. The bulls I see these days are the same tune. Good none the less, but the simmental breed needs some different stuff. If someone developed an outcross bull that would work on dream on/meyer/powerstoke females that person could write his own ticket.
