I own a 7 year old 16.2 piebald warmblooded gelding, how's name is Spirit, for his spirited personalty.
I was only doing hunters (3'0) and was also riding a black 16.0 warmblooded mare named Cloud9. I was showing her (3'3) Cloud is 15 so a bit older.
I got 2 first on Spirit's and a 2ND. And 3 firsts on Cloud!
