my Pro said "nearly everyone I see plays with a putter that's too long"
A couple of months ago I suggested to a forumer (unfortunately can't remember who) that he spent a fiver or so in getting his putter shaft cut down and re-gripped and give it a try before taking out a re-mortgage on buying a new one. It worked for me but never heard how it worked for him.
Being a bit of a cheapskate, I've had the same putter for about 10 - 12 years. Average about 32/34 putts a round so that's not the main reason my handicap is still cr*p.
