I recently purchased a used 1995-97 Scotty Cameron Newport. It is very similar to the old png Pal putter I have used all my life. I like it and the weight is great but there is no center line on this putter. Not on top of the face or on the skirt behind it. Anyone ever heard of someone milling a small line and putting a little white paint in there? Would I measure to the exact center of the putter face or is there more science to it? I see that some of the newer models of Scotty's have cetner lines and was thinking I could get measurements off of one of those.
