I was recently fitted for a GT2 driver and am getting 1/2 inch off of the shaft. According to my research, every 1/2 inch is 3 swing points -- and 2 grams is 1 swing point. So, in theory I would have to add 6 grams to maintain the same swing weight.
However, when viewing the Titleist web site and the SureFit weight system, -1/2 inch is recommended to add 2 grams...unless I am reading it wrong. So my question is how many grams should I be adding to the head? 2? 6? Swing dependent? The fitter never mentioned this to me.
