I'll be pleased if he will hold a nice canter with a nice headset for a 20M circle for me! Without spurs and a crop. I tried spurs, but I don't think they work well for me at this point in time, I'm scared I will hurt him.
You will if you have uneducated legs. And the only way he is going to hold a "nice headset" is if you are riding him educatedly from back to front, not holding his face. If he keeps throwing his head up on this 20 meter circle, it is because you are riding him incorrectly.
A good rider knows that headset comes last.
