KSU, OSU, adn TAMU are all powerhouses at the Sr College Judging level, so not only are their coaches good, but their team members who will be helping with the camps are some of the best in the country among their contemporaries. I dont think you will go wrong with any of the camps. Also I havent heard if they are having a camp, but Texas Tech has been dominating at the collegiate contest lately, and they probably have one of the best Collegiate Livestock Judging Coaches of all time in my opinion, they may be a viable option if they have one.
But all in all you cant go wrong with any of them, all good programs, just pick the one that is closer to you.
