What is the main difference(s) between the NS8950GH and 950GH iron shafts (R) flex? Does one play stiffer than the other, what about tip flex? It looks like weights are identical – would putting the 8950GH in the 4-6, and the 950GH in the 7-PW be OK? If not, what issues would I run into on the course? Thank you –

Profiles look very similar as do the weights. Balance pt is very close also.
I doubt if I could tell the difference, course I kinda suck!
Sorry for the formatting

Thank you – I thought they were close, and read that the 950GH played slightly firmer and w/ maybe a bit lower ball flight. It looks as though these numbers support that …
