Ping G20 driver is my great upgrade
Used another companies 2 year old technology driver for 6 months, upgraded to the more modern version fall 2010 and had seen improvement (straighter and a bit longer). THEN purchased a G20 and played a round and after a few swings I can say this Ping G20 driver does not produce the side spin of my previous drivers. Quite a bit straighter, all playable shots if I missed the fairway. I noticed I hit the ball a bit longer too being on familiar fairways this year with and without the G20. I would attribute the longer drives to the 0.75" longer shaft on the G20 relative to my previous driver. A worth while upgrade if your playing a 2 year old driver and a decent upgrade for the 2010 lineup of drivers in my opinion. Still going to take some work at the range to grove the swing to the new club. Not sure about people who like to "work" the ball left or right. It may take a bit more animated action to get the cut/draw you desire.
