I have been training my TB (Red) on collection and he seems to do better in English equiptment.
I have been using a twisted wire english snaffle bit and an english bridle on him and it works better to keep his head where I want it than ANY western bits I have used on him.
Plus when I am riding in my english saddle he is more balanced under me. And its not just him.
My mare (Josie) and Charlie are also better at collecting and following commands in English tack.
Has anybody else noticed that?
