If Steve Stricker misses 15 ft of the pin on a 100 yard approach shot more than 2 times out of 10 - we wonder what is wrong with his game.  If I hit 6 of 10 within 15 ft of the pin, I wonder what is right with my game.
 
He uses the D3, I use the D2.  If your strike pattern on driver is withing a nickle of center, you may enjoy the D3.  My half dollar needs all the sweet spot I can get.
