He worked really well for us back on some High Roller/Simmi cows. I had several females from that mating that were really good. I just have one direct daughter left, and a couple of her daughters - I didn't keep any daughters of the others because of their udder quality - they milked good but had some big teats (which could've come from lots of places in that equation). We sold several steers out of him, too, and I do recall some of them having some attitude - not impossible to handle, just enough to be a pain. Structure wise, we didn't get any major problems, but I know some did.
