The AVCOG is helpful when selecting iron heads but only lists the 6 iron (typically.) is that information available for a PW in a set? I hit the ball high, which isn’t the end of the world in a 6 iron but is a killer with the short irons so the AVCOG of the short irons would be great for me for selecting which heads to choose.
Thanks!
Measuring the AVCOG on all the heads in a set the way we do for the #6 irons and the MPF is something Ralph did and illustrated in his MPF book to show how the the AVCOG varies as the head shapes and lofts change within a set, but it is not something we can do for all models of heads we publish like we do for the #6 irons and the MPF data base. You can get a pretty good idea by simply balancing the PW on it’s face using a pin punch, or a pen, or something you can secure in a vice. That gives you the basic VCOG. The AVCOG will then be slightly lower based on how how far back the rearward cg is. It’s important to realize that the AVCOG in wedges has a extremely minor effect on trajectory. Loft has the overwhelmingly major effect on the trajectory of the higher lofted clubs. When you see the Tour pros hit “knock down” wedges or sand wedges, it is NOT because the wedges they have have a higher vertical cg, it is because of their technique. I know some wedges have features of higher vertical cg’s to “help control trajectory”, but it is very difficult to say that a few mm higher cg location on a wedge will reduce the trajectory by X amount. Trajectory produced on wedge shots is primarily controlled by the loft of the wedge and the technique employed. Shaft type, specifically flex, might have a little to do with it as well (more so than avcog), but still is minor compared to the loft.
