The Precision Rifle Project X has been with us for a very long time. It somehow got missed when I was in the early days of measuring the vast number of shafts in the market. I noticed its absence when I measured the Project X LZ model. It was originally made by Royal Precision Shaft Company in Connecticut. They were acquired by TrueTemper and the production was moved to Tennessee.  You will see many of the best players in the world playing this shaft. Compared to a Dynamic Gold X100, it is slightly softer in the butt and stiffer in the Mid. Unlike the TrueTemper Dynamic Gold, the  Project X profile is the same for all weight/stiffness variations. The heavier the shaft the stiffer it gets. The profile remains the same for all flex designations.

This video was sent to me years ago by Dave Eagar, who mentored me when I first began measuring golf shafts. It is a brief history of the Royal Precision Shaft Company and a tour through the Royal Precision facility and manufacturing process. It is presented by Ron Chalmers, then President of Royal Precision with Dave Makarucha of Accra Golf Shafts as camera man. ACCRA was recently acquired by True Sports, parent company of True Temper.

Lets look at the profile:

The measurements are available only to registered readers

My friend and mentor, Dave Tutelman posted this comment in another discussion of the shaft stiffness range metric. I cannot express my thoughts about this new metric any better than he did. “A big advantage of “measuring” shaft stiffness by plotting the EI curve is that you can do mathematical operations like this. You chose a simple one, with simple arithmetic. But it isn’t that hard to use a butt-biased weighting function that will predict frequency, or a tip-biased weighting function to predict trajectory height. The combination of a known EI profile and spreadsheet capabilities means it’s just arithmetic. As we understand shafts better, EI will not become obsolete; just the way we use and display it will.”
