I am really tempted to reshaft my 302 with Modus 3 after hearing so much good comments here, currently I have C-taper in S flex on my irons and the club maker recommended to go for X flex for Modus as NS pro tends to play one flex less, I just have a little bit of hestitation if X would be too stiff for me. My 6 iron ss is 85, strong late release.
