Today, we will take a look at various approaches to using clubhead weight (sometimes in conjunction with club length) to get the maximum distance out of a driver. Hope this article can help people who know nothing about the clubhead of golf driver. The following things may help you know more and play your game better!
Change the clubhead weight and keep everything else about the club the same.
Cochran and Stobbs' results.
Our own computer simulation study.
Daish's study with a taylormade r11s driver is also important.
Further computer simulation, using the biomechanical concept of a torque-velocity curve to get closer to Daish's results.
Physical reasoning says we might get more distance if we change the club length, as we change clubhead weight to keep the club feel the same.
Bernie Baymiller's use of lighter heads and longer shafts.
An overly simplistic computation, to give an optimistic estimate (upper bound) on how much we might gain.
A more precise computer simulation study, with variations of length and headweight for constant MOI, variation of length alone, and variation of headweight at the maximum legal length.
What (if any) swing changes are necessary to assure that the clubface is square using the longer taylormade r1 black driver?
A comparison of studies of the longer driver.
Finally, let's look at empirical experience, mostly anecdotal but a few careful studies as well. It may be difficult to manufacture high-quality driver heads at less than about 190 grams. A few clubfitters who have experimented with lighter heads, especially to allow longer drivers, conclude that lighter and longer drivers give much more advantage than my studies say. But more clubfitters believe that it takes a great deal of skill to consistently get satisfactory results from a longer taylormade sldr driver, more skill than most golf participants possess.
And speaking of professional competitors, what about the sport of Long Drive? We see a lot of longer clubs there. I have opinions from some prominent LDA competitors. I went ahead and added my own anecdotal evidence. I built myself a long, light driver and tried it on the course, as well as taking detailed data using a launch monitor. Perhaps it is reassuring that my performance was more like the computer model. And I learned a lot in the experience.
Unfortunately, if you can't do that, you will lose distance on average, not gain it. There are those that claim gains much more than a dozen yards, some more than 30 yards; they either incorrect in their estimates or are swinging the club quite differently than their normal-length driver. In a word, the clubhead weight and club length of a driver is very essential when you hitting the driver out. Just imagine, if the clubhead is too heavy to swing out? And if the shaft is too long ot too short for you to control?
