I actually saw Mr Gus 80c as a mature bull in 1996 and 1997 and probably 100 calves and 50 bred heifers and at least a few 3 year olds. I will tell you that he looked a lot like Marquis 86G, but he should they have the same mother. I have video of him, but I don't think I have a picture. I hated his picture in the Alta Sire directory, but his calves were awfully impressive and so uniform that you could pick them out after a short while. Troy based on what I saw in your herd, you would have liked 80c.
I believe the mother of the bulls was 14 or 15 years old when they culled her. Awesome cow, very deep and lots of spring of rib (have her on video too). To me she was the reason that both bulls breed well. All of my experience with 80C and a son of him that I bought was easy calving and easy fleshing. Daughters and grand daughters were real nice and had some longevity. I have been using Studers Trendsetter (Marquis son) on some 80c grand daughters. Results look quite good thus far.
I don't like the picture of Piper either, but it looks similar to 80c's picture when he was young. Not saying I will use him, I would have to see some progeny first. I am not as good as some of you are at picking the best calf at birth. Some bulls' calves look the best they ever will, the day they are born and go down hill from there. Others I have seen look better everyday of their life. Maybe I just don't have as good of an eye as others. But I know what has worked for me. If any of you have any of that old 80c semen that you want to throw away, I would be glad to take it off your hands!
Good luck with the A&T Renegade calves, I saw him as a calf and liked him. I like A&T's program, you should all get there sometime, tough environment, and good cattle rise to the top in that system.
