The
Callaway Big Bertha Diablo utility clubs have been designed to be long,
forgiving and extremely accurate. DRS technology allows better turf interaction
from various different lies. DRS stands for Dual Rail System which you
can see from the pictures are the 2 rails running from the face to the
back of the club.
The DRS also lowers the leading edge of the club allowing the sweet spot
to be more accessible. The high Moment of Inertia of the Diablo utility
makes it highly forgiving and amazingly accurate whether you are using
it off the tee or from the fairway.
