I definitely know what you mean. When I went for my trial ride on Zeus we had a gallop on the straightaway and oh my GOODNESS that horse can MOVE. We were cantering along and I could feel him ask me if he could gallop, and I just let him go. It was amazing. I've never ridden a horse with so much power before and I LOVE it.
I can't wait until we get to the point where we start jumping him again. I popped him over a smallish jump that was out in the field and his jump is so round and, just, wow. He LAUNCHES. Ha ha. I'll stop babbling now.
