This experiment aims to test whether a grooved grip benefits golfers in any way. A few hypotheses were tested.
Hypothesis 1: With the grooved grip, the player will be able to feel the driver’s head and have a better feel of how the face will be at impact. This will result in a better dispersion.
This is tested on trackman and data of shots with and without the grooved grip are recorded and analysed.
Hypothesis 2: With the grooved grip, the player will be able to align the driver head, on top of Hypothesis 1, the hits should be more centred on the driver face.
This is tested with a Markit Spray and hit on both normal grip and grooved grip.
Hypothesis 3: As the grooves are a form of sensory aid, the training value should be tested. After hitting multiple shots(in this case at least 20), we test to see if there is any residual effects after switching back to the normal grip.
This is tested on both trackman and Markit Spray and analysed to see if there are any patterns.
Golfer will hit with his driver and Wizgolf will fit them with a driver to achieve maximum efficiency first. If the golfer’s driver is already at maximum efficiency, they will be fitted to something identical.
They will hit 5 shots with Markit Spray on the face. Then the grooved grip will be swapped in and they will hit 5 shots with Markit Spray. After that, they will hit another 15 shots to feel the grooved grip which will link to the last part on training value of the grip. A normal grip is swapped back again and tested with Markit Spray. Throughout the whole test, all data are recorded on Trackman.
A total of 46.15% of participants experienced an improvement in ball dispersion. Of this 46.15%, the improvement in ball dispersion ranges from 10% to 80% (but mostly see a 10-20% increase).The other 53.85% did not experience any visable improvements in ball dispersion.
For the Ball pattern test (or otherwise known as the Markit Spray test), a total of 46.15% of participants experience more centred hits (Note that a player may experience a better ball dispersion but may not see tighter ball patterns on the driver face). An example of a golfer benefitting from a grooved grip but results also suggests that there isn’t training value for him.
For the training value test, 30.77% of the golfers see centred ball patterns after changing back to normal grips. This suggests that the grooved grip may have training value to some.
The data that were collected shows little correlation between handicap levels and changes in the dispersions.
Comments from the participants
38.46% of the participants commented that they can only feel the grooves during the setup but not during the swing. Interestingly, most ladies commented that the grip feels uncomfortable as it feels as if it cuts into their flesh.
In retrospective, the Grooved Grip is beneficial to many golfers but not all. Perhaps you should try to find out!
