CG is the name of the game for the new Cobra S9-1 Driver. The all titanium driver has been downsized to take advantage of each loft. In addition to the optimized CG, rather dramatic changes have been made from last year's model such as slightly narrower face and less crown surface area. The weight has been reduced by almost 6 grams to increase club-head speed - this to me is a biggie. I am an advocate on stripping unnecessary weight to increase club-head speed. This is the name of the game to gain additional yardage, for maximum effect.
Other notables for the Cobra S9-1 is the new Hotter 9 Points technology to further increase clubface efficiency. What is this? It's the design of the driver to maximize COR using a Dual Rhombas insert to promote higher ball speed and a more consistent ball flight across the entire club face.
Comes in three different models (excluding the S9-1 Pro): S9-1 M for swing speeds of 87-108 and ball speeds of 125-155, S9-F for swing speeds of 97 or less and ball speeds of 140 or less and finally the S9-M (offset) for swing speeds of 97 or less and ball speeds of 140 or less.

Actual Player Feedback-

"Feels great and goes straight"
Absolutely great looking driver. Cobra has always come out with stellar drivers and this one is no exception. Very high MOI and balanced face makes this one of the straighter drivers on the market today. Excellent custom shaft selection such as Graphite Design, YS-6+ and YS-7+, Aldila DVS, Aldila NV, Grafalloy Prolaunch, Proforce V2, Fujikura Speedax, Rombax, and the Mitsubishi Diaman to name a few.
Driver is probably more geared for the average player. Lacks lower loft selection (starting at 9.5) unless you go to the Cobra S9-1 Pro model. These are not negatives to the majority of players however...
The Cobra S9-1 is definitely a great driver for the average to better than average golfer looking for distance and accuracy. A high launch driver that's straight and long, this is the general consensus. Made Golf rating in the Golf Digest Driver reviews for 2009'. This is definitely a driver putting on your short list this spring.
