How many inches do you need to tip a driver to move it to the next flex?
Specifically I’m thinking about an Aldila NV44 Magnum
It can vary from shaft model to shaft model. The issue with the Aldila NV 44 Magnum is that ionly has a 2.5″ parallel tip section length, which does not leave much room for tip rimming. Aldila does not recommend tip trimming that shaft. You could trim it 1/2″ to try and stiffen it up a little, but that might only get you about 1/3 to 1/2 a flex.
