In any case, it's Ping G15 Driver!

This best Ping G15 Driver shines in the forgiveness department, although Tatsuro did not notice if there was any new technology in it that actually gave it a clear advantage over others he did find it very forgiving and equal to many game improvement drivers currently on the market. When put through its paces and purposely hit off center he compared it to the Nike SQ except with better feel.

The Ping G15 Driver is engineered for golfers seekinga maximum forgiveness driver that delivers distance and accuracy. Its 460cc titanium head is longer front to back and features PING's patented ultra thin crown technology. Weight savings from the thin crown are positioned as an external sole weight to optimize the center of gravity for higher trajectories and reduced spin.

I've recently purchased the G15 Driver and was curious to find out the difference between the G15 line versus the new K15 line. Since I bought my Pings from Mygolfwholesale, I always have the option of trading it at 10% loss. That being said, what I've found out will most likely make me keep my Ping G15's and pass on the K15's.
