Don't take people's comments too personally. That is one of the most hardest things with horse people - when someone asks you their opinion and you give them a honest, direct, straight-to-the-point answer based on the horse's best interest, then they don't like it and defend themselves and their initial actions and then give you sh*t why you are 'soooooo rude'. (Sorry - I'm going off on a rant... past experiences on another forum)
I think the video was good because I like the whole bitless thing. BUT the guy does need to improve. The horse tail swishes many times which is a negative thing caused by the wrong stimulus. The guy is unbalanced, his hands are too heavy etc. He needs to learn to be lighter, the horse needs to be given better cues in order to respond better.
But that's the whole idea of posting a video for people to comment on, right? In order to get better, in order to improve, in order to ask for others opinions so that it makes you better. Nothing nasty about that.
It ain't all negative. This guy has achieved alot already. The only thing he needs to achieve is more - which is all of our goal - is it not?
