After much success with Pings G10 I decided to buy PING G15 Driver . My G10 was 9 degrees but I found a G15 10.5 for cheap and went with it. The driver came with a Graffoly Prolaunch Red S. I have read a lot about this shaft and since my ball flight is high I thought it was a good fit on trying to flight it lower. This club is not near as long as my G10 9 Degree with the TFC 129 shaft. Feed back was minimal, severe loss of distance on off centered hits. Ping boosts that this club is suppose to be the answer for that. It was not for me. It is a great looking club and instills a lot of confidence at address. there is a noticeable difference in overall club size compared to the G10. I am not giving up on the G15 until I try a couple of more shafts in it. I would recommend it to anyone looking for the latest 460cc driver with a great look and feel at address.
