I have always used extra-stiff shafts, but Shaft Lab recommends 'L' flex shafts. How can this be?
I have always used extra-stiff shafts but Shaft Lab recommends regular flex shafts. Should I make the change?Making a large change in flex usually requires a mental transition as well as retraining the muscle reflexes and timing. Try swapping to a stiff flex product first; then, if the eventual results are satisfactory, consider changing to regular flex shafts.. Back to Top
An older golfer I tested only generates a moderate head speed, but received a recommendation for extra-stiff shafts. How can this be correct?An older golfer is no longer flexible enough to achieve a full backswing position. Therefore, he/she expends his/her full energy (which may be somewhat less than when he/she was younger) in a much smaller amount of time and distance. This often results in a greater loading of the shaft than he/she used to have (and a stiff flex recommendation). To determine if this golfer needs a stiffer shaft, remember the basic premise of Shaft Lab: a shaft should be stiff enough to be controllable, but as flexible as possible to maximize distance. If this golfer is satisfied with his/her accuracy, then he/she probably would not benefit from stiffer shafts. Back to Top
I have always used extra-stiff shafts, but Shaft Lab recommends 'L' flex shafts. How can this be?There are some golfers who deflect the shaft very little but generate very high clubhead speed (we often refer to this as an 'efficient' swing). They move the clubhead quickly through a long arc, constantly accelerating but without interfering with the smooth club motion by snapping the wrists, 'arm-wrestling' the club, etc. These golfers will typically get fairly similar results with any flex shaft, but a softer shaft (such as an 'L') will still tend to deliver more distance. However, an experienced golfer will experience an adjustment period (often unsettling) when making a radical change such as from an extra-stiff to an adult flex shaft. Is the change worth it? The golfer will have to make that decision. Back to Top
I have been analyzed by ShaftLab four times. Twice the iron recommendation was for an R300, but the other two times called for an S300. Which is correct?Consider the following fundamental diagram: Less < < < < < Deflection > > > > > More L A R S X
Essentially, ShaftLab measures the amount of deflection and
drops that person into a flex category. If a person's deflection
happens to hover over a boundary between two flexes, there are
as likely to fall on one side as the other. To deal with this
seeming inaccuracy, set ShaftLab to pro mode. The same golfer
will still vary between R400 and S200, but this difference is
much more easily understood by the knowledgeable golfer.
