Drive Like Bryson DeChambeau
Would you like to drive the ball like Bryson DeChambeau? Several factors are making Bryson the longest Driver on the PGA Tour. One of them is the massive grip on his Driver. You see, the more energy you create in the downswing, the higher the clubhead speed. Kinetic Energy is a function of speed and mass (weight). By optimizing your Driver's weight, you will maximize your clubhead speed, giving you more distance.
This is how it works.
The optimum weight for your Driver depends on your body. Do you have a lot of fast twitching muscle, or do you have more slow twitching muscle? A simple experiment will tell you the exact optimum weight for your Driver. If your Driver is too light, you will create good speed with your hands, but as the mass is low, not much energy is produced. Further, the energy generated in the downswing is not efficiently transferred to clubhead speed. Almost every golfer plays with a Driver that is too light for maximum distance. If your Driver is too heavy, the speed of your hands suffers, and the energy created goes down.
This is what you need.
In addition to the simple tools you get from Rational Golf, you need to measure your clubhead speed. The best option is a TrackMan or similar launch monitor. If you do not have access to one, you may want to try this out in a club-fitter shop.
From Rational Golf, you can order a hole cutter, called a Shaft Access Tool, an 4 mm hex key (unless you already have one), and various weights that will fit inside your shaft after cutting the hole at the end of the grip. I propose starting with four weights; 10, 20, 30, and 40 grams. You may order this at https://www.rational-golf.com/shop
This is what you do.
You make a hole at the end of the grip using the Shaft Access Tool in a drill or electric screwdriver. You then proceed to make five drives. You then hit five drives with one of the weights installed.
Here is a video showing you how to install the weights; https://www.youtube.com/watch?v=cz61Hm5hV5M. It would be best if you do not tighten the weights too hard for this experiment. Then it is easier to remove them. Any mishits should be deleted, and the shot repeated. In this example, you will hit a total of 25 Drives.
Make sure you get some rest in-between the five sets. You record the clubhead speed of every shot. You delete the two lowest clubhead speeds from each set and take the average of the remaining three shots. You can then plot the graph of clubhead speed as a function of weight added and see for which weight the clubhead speed is maximized. It is a good idea to plot this in an Excel Spreadsheet. If you send me an email, [email protected], I will forward you a simple spreadsheet. Using a spreadsheet has the advantage that it can tell you if the optimum weight is somewhere in-between the weights you used for the experiment. Note that the weights from Rational Golf are available from 6 grams to 100 grams in steps of two grams. These weights fit every shaft in the market.
The resulting graph will look like an inverted U. The top of the graph is your optimum weight. Here is an example from an experiment I did with a World Long Drive Champion. An average clubhead speed of 138.5 MPH was achieved with a Total Driver weight of 338 grams. Further increase in clubhead speed is expected as you get used to the new weight.
For further improvement in distance and consistency, you should experiment with the ball position.
Once you have optimized the Driver weight, you may want to let the BioMatch Algorithm optimize the weight of all your clubs so that you can groove one consistent swing for all your clubs. BioMatch will provide better dispersion with all your clubs. Find your nearest BioMatch Fitting Center at https://rb.gy/fzjxu6 or visit www.rational-golf.com
