new to putting segment

[brownman]

Hi all, This is a first for me,Ive never sat back and had a good look at my putting,BUT,I am getting so much better at overall game and I now realise that to really imptove I need to look at flatstick part of my game,
My set-up is as follows
1. I tend to putt using more hands than shoulders
2.I swing putter in straight line back and through
3.generally open stance with back foot square to line of putt
4.on average my putts generally go 12" past hole,when missed

Any thing from tgmers on putting....TERRY
