See, now you're just shooting down advice before trying it, and why ask for advice when you're not going to listen and consider it before saying "No, that's not his problem."?
A barrel horse becoming sour isn't just going to show as a gate issue, it shows everywhere. In the gate, barrel work, at a show, at home..Seven events on top of eachother like that is just too much if you ask me. If you are properly warming him up and cooling him down between those runs you shouldn't have hardly any time for him to relax and calm down..The excitement, nerves, and stress convey to him through you and basically he's worked up and stressed all day. A horse can grow to hate that stress and start to hate that job.. This can also trigger his being "jiggy" on trails, he's now associating you riding him with being excited and working. So in his mind, when you're riding, he has to be on his toes and work.. If you go to a show, you don't always have to do those fun events..concentrate on barrels if that's what you want to keep doing in the future and get serious with.. There is also the chance that he just isn't suited for barrels, it can be too much on some horses and they can break down after doing it. Bad habits can always be worked out if you, as a rider, can stay consistent with the retraining process of those habits and realize IF you are causing the problems...There are always different sides to a story..Your's, Outlaw's, Your trainer's and the truth..Consider all options.
