Ernie Els switches to new UST driver shaft

Erni Els Ernie Els, who switched from Callaway's FT-5 driver to the FT-9 earlier this season, also recently made a shaft change.

The South African has been using a Fujikura Speeder 757 for several years, but changed to a UST Mamiya ATTAS 76 shaft in his driver.

According to UST's Randy Stuart, the ATTAS shaft has a special woven carbon fiber material in the butt section that increases the shaft's hoop strength, making it extremely firm and solid feeling. The ATTAS also features a rigid mid-section that is made from high-modulus graphite.

The ATTAS is different from the popular yellow and black AVIXCore Tour Red (used by players like Davis Love and Stewart Cink) in the tip section. That shaft is extremely stiff in the tip, but the ATTAS is relatively flexible.

Stuart says that because so many clubhead makers are now focusing on increasing the moment of inertia (MOI) and making products that are inherently more stable, shaft companies can use a more-flexible, feel-enhancing tip for fast-swinging players.

In the heavier shaft weights, it will take a lot of swing speed to maximize what the UST ATTAS shaft can do. However, Stuart says that when the shaft is released to the public there should be lighter options more tailored to weekend players.

Look for the UST ATTAS shaft to arrive in specialty club fitter stores late in 2009 for about $350.
