Help with a colt

We raise bucking bulls and have broke several colts ave messed with several problem horses. What works best is a little brother that can stick it to a rank one and a buggy whip. Get somebody to ride her in the round pen and start her off slow and gradually get to that good lope and keep her moving with that buggy whip. They may buck but they figure out your not getting off and the whip only gets worse. If that dont work I got a buddy that trains horses and uses alot of clinton anderson techniques.
