When I first got the horse I'm competing, I had to shorten my stirrups because he has so much SPROING...he'd throw me so high at a trot I'd lose my stirrups (especially going by cows). He's also a pro at the big shy, combined with the whirl-and-run. I ride in a Wintec Pro Endurance, which is not a very secure saddle, and in going over our latest big shy (today), I find I tend to sit deep and grip with my thighs and seat while reaching up to grab his bit on one side to pull him to a stop. At least he's a small horse!
