I have a question regarding the shape and COR of the AP2 irons.
I am testing the AP2 vs the JPX 825 and asked a question regarding the shape of the Titleist irons.
My question was, why is the shape of the JPX825 more rounded in the longer irons than the AP2?
The response I got back (from miz) is that quote
"On the 825 line, the longer irons are designed to be not only forgiving, but also to have the highest COR possible in the long irons, flowing down to a more traditional iron design COR in the short irons where distance is not as important. As the set flows, the longer irons get a bit more rounded in shape because the roundness of the topline and leading edge actually help to increase the effective rebound area and increase the overall COR. Think of a trampoline. If the trampoline was shaped like a traditional iron face gauge (relatively straight on the leading edge and top with a taper to it), then the COR and amplitude of rebound will be less consistent and maximized across the face. A more rounded shape, however, allows for a bigger trampoline resulting in a larger rebound and also a more consistent one. This is why the head shape flows as it does, eventually ending at a more traditionally shaped set of short irons."
That being said, the AP2 line is not designed to have increased COR at all throughout the set, so they follow a head shape flow that is more similar to the models in our MP line of golf clubs
Can I get a clarification from Titleist on this!
