In irons particularly, how much of the 'soft' feel is down to the club head itself, and how much to other factors? Change a shaft and/or ball, and you might get different results.
I agree with this statement, I know my personal experience with the razr x and razr x tour irons the shaft I believe was the biggest difference in how the iron felt on mishits. The razr x was very harsh and actually hurt my hand after a few really bad shots while the razr x tour was not, I could tell when I didn't hit it well but my hand didn't come away numb afterwards. Now I don't know the exact manufacturing difference between the 2 heads and maybe the tour is buttery soft compared to it but in my head I attributed the feel to the shaft and not the head itself.
