PGA Show Buzzz- Project X PXi feels softer than other PX shafts and is lighter with minimum trajectory problems. As you go lighter the ball goes higher in most cases and Project X PXi manages this well.
The new shaft is lighter (116 grams in the 6.5) than previous versions. As a comparison to the Dynamic Gold that is 128 grams this shaft has shaved off 12 to 14 grams depending on flex, and it is noticeable. The inner profile of the shaft has been changed. They took weight out of the center part of the shaft and moved it towards the butt and tip sections so the shaft plays a little more tip stiff. Because the tip plays a bit stiffer, they actually been have able to keep the same flight trajectory & spin characteristics, which means more distance. Greater distance by virtue of reduced weight properties. Tour-caliber spin control and tip stability in a lightweight package…hallmarks of the PX franchise. Improved feel through optimized butt to tip stiffness calibration.
