Richard,
I am pleased that you enjoyed my book, thanks for mentioning it.

There are various reasons for pros changing putters, a few of which are that they are being paid to do so;  they are still looking for that magic wand; their putting stroke has gone sour and have nothing else to blame; or they just believe a change will be good.

I think that Tiger’s change to an almost identical putter to the one he has used for years, and then the sudden shift back was more a mental issue than putter performance. Once you have developed confidence in your putter I suggest that you don’t change. Corey Pavin has been putting with a Bulls Eye blade – this was a great putter in its time about 50 years ago -- and has done so for as long as I can remember. KJ Choi was doing reasonably well with his standard length putter with a bigger than usual grip and then made a drastic change to a modified side-saddle style with a long putter under his armpit. This has not done KJ any favors.

Richard, it is very important that you first get a properly fitted and well designed putter – 90% of us should use a mallet putter with a low center of gravity, a high MOI (forgiveness) and face balanced.  Then you need to work on your putting. I say this because we don’t spend enough time on our putting technique. About 40 % of our time is spent on the green and this is where 45% of our score are generated. But we spend less than 5% of our time on learning and understanding how to putt. A good putting lesson can help you enjoy your game.  

We teach the twelve fundamentals of putting in our Putting Studio, which are based on our experience in mechanics, psychology, green reading, rhythm etc. and input from our very well qualified advisory board who conduct research on putting, as it relates to their respective disciplines.
