This blade uses the Butterfly VIS structure, with the balance point in the middle. PRO-01 is better at holding the ball than Vis in style, and the speed of hitting is not as fast as Vis, but the depth of eating the ball is higher and the control of the ball is stable. Model: Pro-01 Layer: 5+2ALC Brand new in packaging. It is a flared handle grip and has never been opened still in its plastic film. This blade is alternative to Viscaria.
