It seems to me the best way to see if this driver really makes a difference is by looking at the scores of those who have it and seeing if their average has gone down since buying it. I checked a few profiles of those that have the driver and found most of them play so many rounds their scores before they bought the R1 aren't shown.
Anyway, I have the figures for 2 anonymous players. Their average for their last 10 rounds before buying the driver and the average of their last 10 rounds played.
Player 1 before R1 = 57.9 after R1 = 55.7
Player 2 before R1 = 59.4 after R1 = 57.2
I realise this is too small a group to draw any solid conclusions and we have to bear in mind they probably use the new slower meter Nike ball which might account for a shot per round.
Whatever the cause, dropping your average score (not WGT average) by over 2 strokes since early March is pretty good going, something must have changed for the better.
