Hello, my first post but I have to say my bit. The logic of putting a heavier shaft in a three wood than a driver is completely confused. The three wood has a shorter shaft , which by definition makes it stiffer and compensates for the extra weight in the head. I have a ping G 15 60s driver and the matching 3 wood with a 75s which is the standard configurationsfor these clubs. I love the driver can’t stand the three wood - it’s too stiff and I can’t feel the head. The same weight shaft should be in both . Thank you.
