I have searched to no end for this answer. I just wanted to see if anyone out ther who has had both in hand at the same time and could give me an idea on how much bigger the AP1 head and face is compared to the AP2? I mean is it like going from a players blade like head to (please excuse the old term here) a so called compact mid-size or is it like going from a small blade like head to a (and here is a throwback) Tommy Armour Ti100 (which was the size of a mack truck front grill. Thanks to any and all help and info.
