A gigantic 460cc head (biggest footprint in golf says Nike) with a tall face that’s made of layered yet tightly compressed titanium called NexTi, developed exclusively for Nike Golf is the main characteristic of the Big Foo… I mean Sasquatch tour driver. NexTi is supposedly thinner, lighter and stronger than conventional titanium.
This is the "tour" Sasquatch version, which basically means "no newbies allowed".

The Ping G5 driver must be one of the hottest and most wanted drivers introduced in 2005. Its giant 460cc head with improved internal weight placement gives the G5 a greater moment of inertia, providing more stability, control and forgiveness. Other notable features include the web crown design, improved variable face geometry, robotic plasma wields (high tech people!) and lofts up to 13.5 degrees (offset versions available as well). 
Here she is - the Bertha! This beauty is probably the cause of many golfers’ wet dreams. A lot of stories and reviews have been written about the Big Bertha 454 titanium driver so you probably know all there is to know about this driver, that’s why I won’t bore you with technical details about the Bertha. There is one thing I’d like to point out though. This is Callaway’s biggest (454cc) rule conforming driver, and a big club face usually means the golf club is forgiving to small errors we all occasionally make (or not so occasionally in my case, but that’s another story). This means that the Bertha, with its 454 cc titanium constructed head, should help you a lot on those few bad shots.
