Tried it today. The greens had been hollow-tined and sanded so not the best test but it still didn't do me any harm - 32 putts for the round which is pretty decent for me. (I did have one chip-in though.) I think the simple fact of getting into the putt quicker is good for me, less time for any doubts to creep in. Just pick line and hit. So far so good.
