How to fix the flat stick woes
PUTTING, like a full swing, has general principles that need to be adhered to if you want to consistently putt better. 1. Your palms should face each other before your fingers wrap around the grip. 2. Your front eye should be directly over the ball so your eye can get a 90 degree perspective of the line. 3. Your forearms must be in line with your shaft which will put your grip parallel to your lifeline on your palm.
Therefore, I recommend: 1. You carry a splint finger, which is your left index finger pointing down the shaft, overlapping the back of your right fingers.
2. Try and lock your knees straight to remove unwanted movement with your legs and hips and this also allows your head to get over the ball. 3. Your shoulders start parallel and also level to keep you down and through the stroke a lot longer.
