Depending on the level you are showing (local, registry, etc.), I'd possibly show him in EVERYTHING depending on if you like to show in everything and if he enjoys it... and if there was some kind of high point award I was after where all classes count. Some of my personal favorites because I like them are showmanship and obstacle.
