tibbets: YJ, If you haven't tried them how would you know? :)
I started by saying that it was observation based only.
The accuracy of those 3 irons isn't the same. I'm assuming it also affects the spin capability-would make sense because I saw the difference by using it (the 85 yd w) until I got master and rearranged my club scheme.
I would bet this difference is lost on the vast majority here anyway. I'm happy by thinking I have what I have-seems to work.

....and yes, I do play but 5-10 under bogey golfers have no business thinking they can spin the ball! ;-)
