This is my first real post, I've been reading for a while, just never had anything to ask. Anyways...
The irons I currently play are the old Ping eye 2 coppers. My father recently got a set of the Callaway x18s and I hit them one day when we were playing. I was much more consistent and had 1 1/2 to 2 club lengths further on distance. I am planning on getting a new set of irons soon, and I am pretty much sold on the X series.
My question is, is there any real difference between the 18s, 20s, 22s that is worth the price increase? If there is I am willing to upgrade to the 20s and possibly even the 22s, but I wanted to hear what the forum had to say before I tried them out again.
Thanks.
