Well, yes. Like the picture says, it can effect accuracy and it can also affect trajectory. That's why you should have a fitter look at your swing and suggest a shaft to fit your strength...my guess is that you're a pretty strong guy with quick hands. I'm guessing, without really knowing, mind you, that you're too strong and quick for a regular flex...but there are other factors like torque and kickpoint to consider as well. You might want a fitter to take a looksee.
