Field Notes
Notes from the bench — plain explanations of the shaft variables that shape ball flight more than most golfers realize.
Shaft Spine Alignment Explained
What flat-line oscillation testing actually finds on a shaft, and why orienting the spine consistently can tighten dispersion.
Read article →Kick Point vs. Flex Profile
Why two shafts with the same flex rating can launch the ball completely differently once the bend location is factored in.
Read article →Swing Tempo Ratio
Why the ratio between your backswing and downswing should set your shaft weight class more than your clubhead speed alone.
Read article →Shaft Torque, Explained
What torque actually measures, and why lower isn't automatically better for every swing type.
Read article →Static Loft vs. Dynamic Loft
Why the loft stamped on the head rarely matches the loft actually delivered at impact.
Read article →Swingweight Isn't Total Weight
How two clubs can weigh the same on a scale and feel entirely different in the hands — and why that matters for fitting.

Reading about shaft mechanics is a start — seeing your own numbers on the deflection board is where it actually clicks.
