Happy Fourth of July all. I am not in the shop, but my alleged mind is still working. In speaking with a long time club tech, I was discussing reshafting a 355 steel taper tip shaft in an iron with a parallel .350 graphite shaft of equal flex per the owners insistence. He was adamant about trying the graphite. My colleague advised me that I needed to use a . 350 taper tip graphite shaft. I was under the impression that a graphite taper tip shaft could not be made as decreasing diameters of a graphite shaft led to a weakness. I would like to know if a .350 taper tip graphite shaft is made and if so by who?
