Haven't purchased yet, but got fitted today for AP2 S300 Dyanmic Golf AMT White shafts. A goal is to hit the ball higher and it appeared to work in the simulator. I am confused as the charts say the AMT Red shaft should add a higher trajectory. The AMT White is 25 g heavier. Is that what would make the difference? Wanting to make sure I get the right shafts. Any thoughts.
