When your golf-industry competition claims to have the longest driver in the market, you can't be content to let those claims go unchallenged. So, Callaway - which has created many iconic drivers in its history, including the original Big Bertha - has answered with the Callaway Diablo Octane Tour Driver. The equation is relatively simple: longer shaft (arc) + lighter weight = greater clubhead speed. Greater speed = longer drives.

In the case of the Diablo Octane Tour Driver, the crown of the club is created using this process. You can actually see the material in windows on the crown itself. The weight saved using Forged Composite instead of titanium allowed designers to move more weight lower and farther from the face, which helps to lower the club's center of gravity and make it easier to get ball up in the air. You can actually see the Forged Composite in the head.

The Ping K15 Iron is a new breed of iron set. They are made with a titanium face and a stainless steel body. This will help to increase the forgiveness and it will also give you the best possible launch angle for your game. The best part about the Ping K15 iron is that they are built for lower spin and a higher ball flight. This means you can land the ball softly and stick it on the green right by the pin. 

The one negative about the serie de fers Ping K15 and hybrids is that they are not made for highly skilled golfers. If you are a single digit handicap you have very little to gain from this set and you might actually play worse with these. This is simply because those that are highly skilled know how to control the spin of the ball and want to create spin. These clubs are made to reduce spin so they will not fit into this type of golfer's game very well.

The K15 Irons have been designed to give golfers the ultimate in performance and flexibility. Introduced as a replacement for the company's Rapture irons, the Ping K15 Irons use multi-material construction a wide sole, and perimeter and sole weighting to promote a high trajectory, stabilize the club head through impact and enhance forgiveness.
