It's along the same lines, yes. There are 2 procedures done to shafts to determine playability.
One is called 'spining' (not spinning), and the other is called 'FLOing' (FLO stands for Flat Line Oscillation).
There's a fellow by the name of Dave Tutleman that has done some excellent work on both.
The general theory is that the shaft will have one plane that it constantly wants to return to. By aligning this plane in all shafts across all
clubs, you gain consistency across your set. Before you ask, no, the OEM's do not do this. Not one.
"So what?" you say. Well, imagine if the plane of return ran from 11 o'clock to 5 o'clock on your shaft. When you swing the club, this is the plane in which the shaft will want to ultimately move. Yes, the force of your swing is greater than the natural bending tendencies of the shaft. But when it kicks, the natural bend is going to influence the kick. It may not directly change it, no, but it will certainly influence it. "No biggie," you say. "I just make a small setup change to counter that." Fair enough. But lets say that the next club you grab has that plane at 9 and 3. Do you make another setup change? And if the plane is 12 and 6? What about 10:30 and 2:30? (That's a joke. If that's your plane, your shaft is bent or broken.)
I don't make
clubs that haven't been FLOed. IMO, spining is a secondary procuedure, where you can enhance distance or control.
