Can someone compare spine Black Eagle vs Gold tip 350-340

[Tedd]

Thank  you in advance if someone could compare with a spine tester the  Black Eagle .350 spine vs Gold Tip or Trad Only.340 spine.
I know the Black Eagle .300 is a lot stiffer than other .300s.
Actually I just spine tested a bunch of carbon shafts. There is a 9lb spread on shafts from different manufacturers that are all marked .340.
