I've had a few, so my sample size is relatively small. Born easy out of both cows and first calf heifers. Definitely adds depth of body and keeps frame size in check from what I've noticed. I have a son out of him that I retained for my own herd. I liked him enough that I have also sampled his full brother (CCR Santa Fe) and a son (BCLR Wide Load). Wide Load added a bit of leather, but like Range, the calves were born easily and have grown fast so far. For what it's worth I've kept them all.
Best of luck to you!
