Generally the ideal way to fit a golfer for iron length, is to find longest shaft that he can consistently strike in the centre. ( yes i know hand to floor meausurement plays a part to, but thats done first not lastl
So a good fitter will have several clubs made up to varying lengths plus impact decals.
What club is normally used for this, like a 6 iron?
But then if we do that, but then 3-5 iron will progressively be too long for me, or am i missing something.
