I need to convert the spine of my Goldtip and Easton shafts to the AMO static spine standardization. They've their static spine declared as for example "500" which translates into a deflection of "0.500". But with which measurement method? The AMO/AMA with 2 # @ 26 " or ASTM with 1.94 # @ 28 "?

  • I truly believe Easton, Carbon Express and Gold Tip use the static measurement method. (a 1.94# weight hung dead centre in the middle of a 28'' shaft)

  • I don't have an answer, but I once called GoldTip and got an amazing person on the line who not only answered my question, but spent time talking about the "why" of the question. I would suggestion trying to call GoldTip and ask.
