It doesn't matter. 10% via any of those methods can't out-gain 15 yards of distance.
The only way 10% more accuracy could matter is if you could take the 10% of your WORST drives and put them in the fairway. Only then might you have a chance, and it's unrealistic that 90% of your shots would be the same, and your 10% WORST shots would be some of your best.
10% more accuracy is not a lot, and distance is a much bigger advantage, especially since we're not playing in U.S. Open type rough (Pinehurst excluded :D).
Hmm. I get what you're saying.
But as a high handicapper relearning the game, my problem is less distance than inconsistency - and with the driver, that tends to mean inaccuracy.
And the game seems a hell of a lot easier from the fairways - the rough at my home course is fairly penal.
On the other hand, i guess the trade-off isn't strightforward. Decent ball-striking will result in better distance without substantial loss of accuracy, so maybe it is unrealistic to treat them as alternatives.
