A stiff shaft is firmer and harder to bend than a regular shaft, and so more often than not, they’re also heavier in weight.
The aim of the game is to match your swing with the correct shaft flex to maximise your distance and control.
Is there a big difference between regular and stiff flex?
If you have a slower swing speed, you are probably going to want to choose regular shafted clubs because the additional flex will provide a little more power and accuracy. When you swing harder, the stiff flex will be more controlled and give you the punch you need to hit better shots.
What swing speed requires a stiff shaft?
Stiff shafts are recommended for players who generate high club head speed. If your swing speed is 90 mph or higher, a stiff shaft or an x-stiff shaft should be a good fit.
Is there much difference between regular and stiff shafts?
The Seniors flex is meant for golfers who swing a bit harder. A Regular shaft is used by golfers who hit the ball an average or farther than average length. For those long hitters, there are Stiff and Extra-stiff shafts that flex little.
What flex should my irons be?
