So.... after about 7 years of off and on work when I had the time, I finally finished my pet project. My refinished Slazenger putter, with graphite shaft and cork grip.
I know a graphite shaft in a putter seems like a slightly left-field idea, but given that the Slazenger has so little weight in the head, I needed to make the shaft and grip as light as possible to give it a better feel.
I have tested it out on the carpet and it felt like butter, can't wait to test it out on the course.
