The last week i have read alot about "Spining" ... NBP (Neutral Bend Point = 90 degrees from spine) and FLO (Flat Line Oscillation) of new shafts. I think it's important to know before the FCT-tip is mounted at the best suitable loft for me.
Several brands have FCT-tips mounted on their shafts. When changing the FCT to lower or higher ... the shaft have to be turned. I have read that there are shafts who have more spines .... but every shaft has a strongest one. Testing is telling me that the best FLO doesnt have to be in the same path as the spine or NBP.
What is the effect when i change the FCT into a lower or higher loft by turning the shaft clockwise or anti-clockwise? The spine ... or NBP ... won't face the target anymore and the best FLO is also not in line with the target anymore.
