maybe test him for a month? Though he has a bit too many As in his other ratings for my taste. I have a lot of frame in my braves though, so I might be biased. Champagne on the other hand is always nice to have
No, don't fire them, but I would switch the dressage, xcountry & jumping riders to AD. consolidate the level 1 horses under one rider. The level 2 horses as well.
