The position of the shaft within the grip increases the angle of both wrists (ulnar deviation), naturally dictating their position and limiting their movement and influence throughout the stroke. This restricted hand and wrist movement reduces their ability to twist or rotate during the stroke, resulting in less unwanted rotation of the putter face and a square impact with the ball each time.
When we play any other golf shot, our wrists are in radial deviation, meaning they are in a cocked position. This allows the wrists to hinge and unhinge during the swing which is crucial to generate power and clubhead speed. However, we do not need power or speed during the putting stroke, we need stability and control.
The higher positioning of the wrists allows the forearms to be aligned in perfect symmetry with the shaft of the putter and putter face. This ensures the hands, wrists, arms and shoulders will work together to allow you greater control of the putter face throughout the stroke.
The Golfer’s Lifeline
If you review any good putting coaches blog post, instructional article or video, you will see that the optimum positioning for the grip while putting is through the lifeline of both hands. By positioning the grip high in the palm, it limits the amount of influence the wrists can have throughout the stroke. However, this is at odds with what golfers are asked to do with their grip for full shots with irons and woods.
With full shots you are encouraged towards a grip that is more through the base of the fingers, allowing the wrists to hinge correctly in the back-swing and follow through. Each P2 grip has been designed so that it sits higher in the palm and fits into the lifeline without any conscious effort on the part of the golfer. What will have felt very strange to the golfer with a conventional smaller putter grip will instantly feel more comfortable with any of the P2 range. Also, as the shaft of the putter is angled towards the back of a P2 Grip you still have the sensation of gripping the putter in the base of the fingers making it feel more natural as you achieve this higher position in the palm of the hand.
Controlling The Smaller Muscles
The P2 core range of putter grips are designed to be heavier than most standard oversize grips to assist a golfer’s control of fine motor skills. Fine motor skills are skills which involve the small muscle groups such as the hands and fingers. These skills use fine and intricate movements for example when playing darts, snooker or putting in golf. Fine motor skills require more control and hand-eye coordination than gross motor skills.
Golfers who putt well have a high level of fine motor skills. This simply means they have the neuro-muscular ability to move and control objects with their hands at slower speeds in a consistent, repeating and very precise manner. For the golfers who do not have a high level of fine motor skill, by placing a substantial weight in the grip, the hands feel that heavier weight and are better able to move in a more consistent manner.
So, if you tend to find that your putter does not move away from the golf ball as smoothly as you would like, or that you struggle to find a nice rhythm or pace to your stroke then definitely consider the Core range.
