With skycaddie & skytrack hit 6 iron average 152 yds 7 iron 140 yds. I think need a A flex shaft. Looking at F2 A 460 es recoil, steelfiber 70 g .355 taper tip A flex, c-taper lite taper tip R flex soft stepped 2X, N.S.pro 950gh R soft stepped, N.S. pro modus 105 R flex soft stepped. Price no factor. I still have fairly high ball flight.  Would any of these shafts work or witch would be better

What are you using now, and what are you trying to accomplish?
