I'm not saying bolting out of the rollback is acceptable I'm saying that barrel horses and powerhouses and many of them try to do it, especially when trained incorrectly to be one as I suspect the OP's horse was.
Personally I don't think any of us are in a position to criticize Sherry at all or any professional barrel racer as they are at a much higher caliber than any of us here. I'm curious to know which runs you are seeing where she has wide barrels? If you're referring to the NFR, that ground is AWFUL, we can't judge off that. Everyone is having that issue.
I think at this point the OP needs to start over on this horse's foundation in general. Relaxed, shutting down, chilling out, then work up. The question was if the trainer could help; And I believe strongly that they can.
I agree with you. I was only giving suggestions to for her to slow the horse down, and to be able to have more controll over the horse, by breaking down the steps, in order to make the horse less ready to bolt off, after the rollbacks, and to have better stopping controll. I think, the one rein stop is acceptable in an Emergency situation, but unacceptable for getting the horse to stop all the time.
Lol, Hey, I'm no Pro barrel racer, but Every video, and every time I've seen her race, she always runs wide. She actually tightened up around the first barrel this year.. I like her, my favorite rider in the nfr. Her horse "stingray" is so much smaller than most of the other girl's horses.. With that said.. I just feel like, If you're gonna be telling people how to race barrels, you should be able to race well in any arena, and in any situation.. That's why I said I'd rather get tips from charmaine james, who has 11 world wins, and In my opinion, is a much better rider, all around.. Not to be offensive.
I agree with you there, but I also believe this is nothing the rider themself can't fix.. Plus, why have someone else train YOUR barrel horse. I never knew a good barrel racer who would let anyone ride their horse on the barrel pattern.
