Offers extra control and helps with outline and turning. The Neue Schule Butterfly Pelham is often sourced when extra control is needed. Helps with outline, turning and lightens the forehand. The butterfly cheeks are excellent for directional control; straightness and turning, hence beneficial for show jumping etc. Highly recommended for children who do not always support their inside rein as the mouthpiece will not slide across to the inside. Popular in the show ring employing two reins or split reins.
