While I'm thinking about it I better jot down a few of the things I'm figuring out.

keeing the face soft in the lead change with soft hands

keeping the horsse in the bridle while turning helps the horse stay soft and turn harder.

Turn, circle, turn. circle and frame turn, circle and frame, turn, circle and frame repeat, repeat repeat instead of turn turn turn traintrainturnhammerturn.stop.

Turn, quarter circle, turn, quarter circle, turn, quarter circle repeat will get them hooked and keep them looking the right way if you repeat it and keep the eye with the inside rein. The results may be more evident the next day.

Always work on turning the horse each direction- even the good way.

Really camping out in the snaffle bit and getting the face and parts broke broke broke will make them all that much better when you stick them in the bridle

If you practice the Dell Hendrick circle drill and guide them back into and through the middle using only the neck rein they will get really light and responsive to the neck rein.
