A little over a month ago I was fitted for 917D and was pleased first two rounds after the fitting how I was driving the ball. Then about four rounds in a row I was seemingly hitting everything right (was set up for fade bias to avoid my natural hook miss). I had two big tournaments coming up and so I switched the weight inside from fade to neutral - and have been amazed with results. Last few rounds have been the best driving period of my life - last Tuesday night in my league hit 6 of 7 fairways - very rare for me.

Led me to wonder - how often have other users tinkered with the weights in their driver head? I rarely have time for range balls, so nearly all of my tinkering happens on the course, hence my hesitation - but curious as to what others are doing?
