For good solid all around cattle type horses I don't think you can beat a retired turn back horse with some Doc Bar and foundation breeding. Their just good solid citizens that can Cut, then go Team Pen, pick up a rope and they'll let you rope off them, then lets go for a nice trail ride.
IMO and not knocking cutters lord knows I love them all but I really think todays cutting world has gotten to hung up on strictly haveing a cutting horse and nothing else. I think the reason Mr San Peppy, Peppy San Badger and alot of that generation of cutting horses were so good is because when they weren't cutting they were roping and dragging calfs to a branding fire and so many other things like turning back. They cut as well and as long as they did because their minds never burned out on it.
