Project X Standard Shaft Detailed Review

Design and Technology

The Project X standard steel shaft is a trusted design that many players love. The stepless design create a non-traditional steel shaft that gives golfers more stability and lower launches. Project X is great for players looking to dial in precise approach shots and tighten up their dispersion.

The Project X standard shafts are my shaft of choice for my irons and wedges. I have played several iron shafts but always return to the Project X offering. I see my dispersion shrink and feel that I have control to hit whatever shot I want to with these shafts. I feel comfortable timing this shaft and would recommend them to any golfer looking to get more accuracy and shot control in their irons and wedges.

To conclude, the standard Project X shafts deliver a stable impact and ultimate shot-shaping control. High swing speed golfers and steep swingers will likely benefit from the more tip-stiff design of Project X. Players that are not as aggressive will likely find better loading and feel in a slightly less rigid profile.

Should You Buy the Project X Shaft?

Fitting your irons and wedge shafts is much more complex than matching your swing speed to a flex or weight profile. Each golfer swings the club differently and creates stress for the golf shaft. Strong players create more force and need a more stable shaft to deliver their optimal performance. The right iron shaft can produce improved club lies at impact and a more accurate ball flight. Project X excels at creating golf shafts for high swing speed players looking to gain control without sacrificing feel and response. Next time you are buying irons or wedges, do not accept what the manufacturer is giving you, get fit and get the best for your game.
