Lady is 6′ 3″ is asking for LTech Hybrid H5. Her 5 iron is 40.5. Following tip trim instructions for LTech medium Ladies flex shaft, I believe that I would need to add an extender that’s about 1.5″ for a club length of 40.5″.

My recommendation is to add a graphite extender not to exceed 1″.  Does that make any design sense in terms of closely maintaining correct shaft flex?
