I only have two, and they're F1s, but they're ~1,250lb functional females and raise calves. He did downsize their mothers little. Made good money selling the rest of the semen while everyone else was still on the waiting list. I wouldn't go out of my way to use him today though.

If you're wanting to use something older from SAV for maternal traits, I have a handful of females by Extension that just do work and a few by his sire that are even better, but those pedigrees probably scare half of agtalk and they obviously weren't created to check the modern epd boxes.
