It entirely depends on the rider and what exactly the rider is looking for out of said horse. For example, if you’re looking for a horse to move up on, one to take you into your first 1.20m, 130m, or 1.40m, you’re going to want one that is brave and not overly careful. But if you’re looking for the winner and can give an accurate ride, you’re going to want something that is much more careful than it is brave. Speed is also important when looking for a winner, but it’s personal to the rider. Some riders prefer a bigger type, with a huge stride that can cover the ground. Others, myself included, prefer a smaller type that may not cover as much ground, but have a faster foot speed.
My first 1.20m horse was very brave and was a great confidence booster. Because of her, I was able to compete at the 1.20m level and I never thought I could. However, she wasn’t particularly careful. I then got another horse and moved up to the 1.30m-1.40m, and he is the winner, but he would throw me off every show for the first 6 months I had him. He is very careful–he will squeal and buck if he even touches a jump. I never could have ridden him when I was first trying to move up to the 1.20m.
