Last summer I stuck one of these (reverse taper) on my Ping G10 driver and now all I hit is straight down the middle and as long as I can remember. Instead of buying a new driver it's worth a try. The driver is a different animal due to the longer shaft and this was my fix. Last round (9 holes) I missed one fairway and that was by a couple feet.
