How do I transition from the fast large circle to a slow small circle?

The transition from a large fast circle to a small slow circle is one of the most scored maneuvers in a reining pattern, and it's where a lot of riders either make up points or give them away. Done correctly it looks seamless — the horse almost seems to shrink himself down, slow his feet, and reorganize into a smaller track without any visible fuss. Done poorly it looks like the rider grabbing two handfuls of rein and hauling the horse down, which is exactly what you don't want. The key is that the transition has to come from your body first and your hands second. As you approach the point where you want to change, sit deeper, slow your following motion, and think about absorbing the energy rather than blocking it. Your horse should feel the change in your body before he ever feels a change in the rein. A horse that's tuned in to his rider will start to respond to that seat cue alone over time. Timing matters enormously. Don't wait until you're already at the spot where you want the small circle to begin before you ask. Start the transition a stride or two early so the horse has time to reorganize without being abrupt about it. A late ask produces a choppy, lurching change that costs you maneuver points regardless of how quiet your hands are. Once you're in the small circle, maintain a consistent slow pace and keep your horse's body shaped correctly on the arc. Don't let him drift out or cut in. The small circle should look just as intentional and controlled as the large one — just slower and tighter. That contrast between the two is exactly what the judge is evaluating.
