Tiny, I never said a word about going forward, and chasing the horse off it's feet around the arena in the name of "forward" is only going to dump the horse on the forehand. One can ride a horse "back to front" in a halt, in a reinback and in short steps, it has absolutely nothing to do with forward, only the direction of the energy. Your seat regulates how forward the horse goes and for something that is ducking behind the contact, often when the hands are taken out of the equation and the legs put on, the horse tries to leave out the front door instead of reaching to the bit. Half halts, half halts and more half halts, a strong core and many transitions are what serve to help the horse stretch and not run, and if you CAN keep the energy moving back to front in a jog or lope without using your hands then by all means do so, it is better than having the horse running around Mach 10 and on it's forehand.
They say money doesn't buy happiness -- well happiness doesn't buy horses!
