As it's 4-H, I'm not going to go false tail. He has a decent tail, and his pasture mate that used to chew on it is now in a new pasture so It should grow back a little. She will be using him for fitting and showing (halter-like class), Western Equitation (WP), and trail for the first year so it sounds like she doesn't need to braid. Neat, clean and crisp appearance makes sense, and trimming extra hair of course. As he is a lesson horse and we will only have a partial lease, I know that he'll getting groomed 4-5 days a week so all that extra hair has long ago fallen off. He won't be used as much next year, but I can't ask her instructor to give him up completely because he's part of her beginner/intermediate herd, and that's where the majority of her students ride right now.
Thanks for the info.
