So I play in a league every Wednesday and have been going to the range atleast once a week to practice. My swing has been pretty good for the most part (for me), but one thing that is constantly messed up is my drive. I have slowed my swing down a lot because I feel like my club is behind on me or flexes too much. Most of the time I either hook the ball or the club stubs the ground and gives me a nasty shot. Out of 9 holes, I probably drive one stright.
I am using a Taylormade R7 Quad 10.5 degree loft. It has a grafalloy blue shaft on it. From what I have read, the blue is a stiff flex. However, I tried the same exact club my partner owns with s stiff taylormade shaft and the difference was so noticeable. The club didnt "wobble" at all on a hard swing and I crushed the ball using it both times off of the tee. Is the grafalloy blue shaft really a stiff flex? Or does stiff flex mean something different for every shaft? In other words, is one stiff flex shaft "stiffer" than another flex? I want to go get a new shaft, but wanted to make sure I am on the right path.
