Buying Guide: Key Considerations For Golf Shaft Flex M

  • Swing speed and tempo: Mid flex suits a wide range of speeds. If you swing faster, consider slightly stiffer profiles; if slower, mid-flex can improve feel and control.
  • Tip diameter and length: A common choice is .335″ tips. Confirm your club’s hosel compatibility and whether adapters or grips affect the installed length.
  • Weight and feel: Lighter mid-flex shafts promote smoother tempos, while heavier options can improve stability. Match weight to your strength and swing style.
  • Router of compatibility: Ensure compatibility with your driver model, including adapters and grip installations. Some shafts are sold uncut or raw and require cutting and fitting.
  • Launch and spin: Mid-flex shafts typically offer balanced launch and spin. If you need higher launch or lower spin, consider a different flex profile or weight.
  • Installation considerations: Some shafts come with adapters or grips included; verify whether additional parts are needed for your club head.
