Conclusion: The Ping K15 driver combines a large 460 cc profile with a longer heel to toe. The design keenly positions the COG [Center of Gravity] low and away resulting in high launch and low spin. Another way of putting it is that it launches rockets! Combined with the SRT technology, this driver is an outright winner.
Pros: SRT Technology and the 10% weight shift is what makes this driver for the masses. Distance, accuracy and forgiveness is the common theme in testing the Ping K15 driver.
Cons: some testers thought it was a bit too loud... but it's all good.
Summary: bought the k15 last month. decided to get one with 12 degree loft. getting more distance and height, and also going straight. i have a g10 driver 10.5 degree loft with draw face. like it a lot and it has been good to me but after only 4 weeks with the k15 i can see a good difference. this is good now and going to get better after i get really use to it!!! i am 66 years old and have had many drivers in my lifetime but the k15 is the best ever!!
