The difference between a lead rope and a standard halter rope or lunge line is that a lead rope is significantly heavier. The added weight makes it easier to convey signals to your horse. The lead rope effectively transmits your hand movements to the halter. It stays still immediately when you stop giving signals, whereas halter ropes or lunge lines tend to swing and create noise when you don’t want it. Additionally, the lead rope is round rather than flat, allowing for better and clearer signals.
