Wellstroke Mat Pro Special/Volvik
This putting guide will help you to reproduce the ideal
movement, particularly as it relates to these three reference
points during your entire swing:
(1). the ideal stroke for control and good contact.
(2). proper clubface orientation at address and during the
swing, to control direction.
(3). the range of the backswing in order to achieve precise
ball-speed control. Mat size: 5.50m x 0.35m / 18ft x 1 ft
