Are All Lacrosse Heads Allowed?
Universal heads are allowed in all levels of play. They follow the minimum pinch and mouth width requirements, making it an easy transition between divisions. NCAA heads allow the mouth width of the head to be narrower, making the mesh sag and grip the ball more at the top of the head.
This will add velocity to your shot and make it difficult for opposing goaltenders. You cannot exploit this in the Youth and High School leagues for safety reasons.
