Isn't Sonyador from Dreamer? lol
You need to desensitize her to the saddle-take it one step at a time. Don't just throw it on there and strap it up. Hold it above the horse, take it away...hold it above and place on its back, then take it away, and so on progressively.
I would take a look at your feed and make sure you're not giving her too much protein...a lot of behavior problems stem from an excess of energy-they're too hot. If she's getting 2 scoops, 4 flakes of hay, and turnout most of the day-that's too much!
