I've been working him at a trot on the pattern for about three months now and he has really gotten good. Just trot up to the pocket, barrel tip the rein and say "easy" and he whips around it like a bullet. He is tall, 16.1, which is big for a barrel horse, I know, and he is kinda lanky, but he can cover the ground and get around turns just as well as my 14.3 full blood Quarter horse. Here is a video of my friend running him, don't critique her, she is a really good rider but my stirrups were too short for her, and blah blah blah:P
I'd also like to try poles on him:) what do you think?
