Ernest and Golfs-for-Fun,
If you can set aside your preconceived notions and what you have been told about grip size, putting a JumboMax Grip on your driver may be the best $11 you will spend on golf equipment. I was a skeptic myself until the inventor, Mike Kachlik, took me to the driving range and let me try them firsthand. It took me a few swings to adjust, but I was hitting the ball so much straighter, I was convinced. I now work for the company.
In the early days of golf, the shafts were made of a small tree, whittled down to be the correct diameter so it would offer the right amount of flex. The club makers then fashioned a piece of leather around the shaft for the grip. It had nothing to do with what fit the human hand. We had to adapt to this too-small size through various gripping techniques which most people still struggle with.
Mike saw this as a potential flaw in club design and decided to explore it further. He looked at other stick sport handles (and hand tools for that matter) and wondered why golf grips were so small in comparison. Baseball bats, tennis rackets and hockey sticks are all much larger, yet they feel comfortable in our hands when we hold them.
Mike began experimenting with golf grips in larger diameters and through his own trials found that they easily outperformed "standard" size grips in accuracy and distance. Testing on hundreds of golfers of varying abilities confirmed his findings. Now it was a matter of developing the combination of materials which would produce a larger handle, offer the correct amount of cushioning and yet retain the torsional strength and twist-resistance a better player would require. The result of his 5 years of development and testing is the patented JumboMax Grip.
JumboMax Grips provide maximum gripping power with the minimum amount of grip pressure required. Because they fit your hands better, you automatically hold it correctly with light grip pressure so you will actually release the club better with more club speed. It is also easier to bring the club face back to square at impact much more consistently.
I know it flies in the face of "conventional" thinking, but it is only because we have all been introduced to golf with a certain size grip and that is what we've come to accept as "normal". Once people see how much easier golf can be using a grip that is easier to hold correctly and control, we think that the JumboMax grip will become the norm.
I hope you will at least give them your consideration, and I welcome any questions or comments!
