People often think the CoG is the centre of the club face, with irons you can get a pretty decent estimate of CoG by drawing a couple of lines on it and it tends not to be in the centre. This sweetspot is where you'd want any marks to be centred around assuming you're wanting centred impact.
If you like I could download that picture, draw a couple of lines and upload as you may find it interesting particuarly when compared to marks on the club.
If you like pal :thup:
Generally I was under the impression CoG will also be affected by weight being moved down and back in the head. That won't be easily measured or translated based on just head shape.
Either way, I'm getting the flight, shape and distance I'm after striking it there, but would be interesting to see.
If you want to kill 5 minutes pal, be my guest :lol:
