WHat are the benefits of using a stiff flex golf club shaft versus a regular flex one?
That first answer doesn’t help you. Here are some facts for you: Knowing you swing speed is important in deciding what shaft to use. As far as swing speed, if you are under 110 mph but over 100 mph, then you need a stiff flex. Less than 100 you need regular flex, and more than 110 you need extra stiff flex. As far as the differences, the stiff flex is designed to snap through the ball in ideal timing with a swing between 100 and 110 mph, regular 90-100, x-stiff 110-120. Again, knowing your swing speed with a driver is important. The stiff isn’t designed to not damage as easily, they are all pretty equal as far as that goes. They will all break if mis-hit, or consistently swung at high speeds. For example, I am a competing long driver, I use an XXXX-Stiff shaft, my swing speed is around 140-145 mph, and the shafts I use only last about 2-4 weeks of consistent use before they break. I worked at a golf course as a pro for some time, and built many clubs, my suggestion to you would be to g
