Beau- equitation is the same no matter what breed or discipline, so it's not a morgan thing. Most morgans are 3 gaited, just like any other horse (some are truly "gaited" they are the exceptions), so their gaits don't change how the rider rides the horse.

Personally, my EQ has slipped over the years and I now worry more about getting the best performance out of that particular horse I'm riding and don't focus on being "pretty". I understand that EQ is about form to function, but I tend to let things slip if they aren't big issues.
