The balance and sophistication of training available from the Brass Clip is most noticeable to me. (If a serious trainer) Pedantic yes but the secret is found in the design which keeps signals traveling in a straight line down the rope whereas the bull clip (not being the same weight and contour all the way through, gives unbalanced wobbling effect to the horse.
The brass clip on these ropes is by far the best clip on the planet for feel, training, natural horsemanship. However, it is not designed for tying horses that may seriously pull back. Use the other clip for that job, combined with a neck strap.
Lead Rope 3.6 m or 12 feet
