i'd say jumping in a black saddle - after all, it only matters how well your horse jumps, not how you look. And most the time, you're too far from the judges for them to notice anyhow. ALthough this depends on the cousre. Why do you ask?
When I bestride him, I soar, I am a hawk: he trots the air; the earth sings when he touches it; the basest horn of his hoof is more musical than the pipe of Hermes. ~William Shakespeare
