The reaction property is the quantified value illustrating the base speed of a blade.
A low reaction property signifies the lower speed of the ball after contact with the blade.
A high reaction property signifies the higher speed of the ball after impact.
The vibration property is the quantified value illustrating the feeling of a blade on impact.
A low vibration property in general signifies slower vibration on ball contact and denotes a blade with a softer touch.
A high vibration property in general signifies faster vibration of the blade on contract with the ball and denotes a blade with a harder touch.
