King F9 Speedback
The KING F9 SPEEDBACK™ Driver is the first of its kind to achieve true optimization of aerodynamics and low CG, making it the fastest and longest COBRA driver.
For the first time, revolutionary Speedback™ Technology combines the benefits of a highly aerodynamic clubhead shape with a low, deep CG, to deliver the Ultimate Formula for Speed.
CNC Precision Milled Face
The industry’s only CNC milled driver face delivers our thinnest, hottest face repeatedly on every driver we manufacture.
Polymer crown trips and titanium sole trips are positioned relative to the direction of airflow around the clubhead to reduce drag for faster clubhead speeds.
Ultralight Carbon Fiber Crown
Golf's first-ever carbon wrap crown design delivers a larger carbon fiber area and saves 4 grams compared to a traditional carbon fiber crown.
E9 Speed Tuned™ Technology
E9™ and Dual Roll™ technologies are optimized for each driver loft, while CNC milling creates precise bulge and roll curvatures to improve driving accuracy and distance on off-center hits.
Front/Back Adjustable CG
An adjustable weight system allows you to move the CG forward or backward to help you fine-tune launch and spin characteristics to improve your distance.
MYFLY8® With Smart Pad™
8 easily adjustable loft settings help you manage trajectory and fine tune launch conditions to maximize distance while Smart Pad keeps the face square regardless of the loft setting.
Premium Aftermarket Shafts
Designed for golfers seeking a lightweight shaft with extreme stability. Helium is ideal for moderate to medium swing speeds seeking a high-launch and mid-spin profile.
Project X HZRDUS Smoke 60
The HZRDUS Smoke is a midweight shaft ideal for mid to high swing speeds seeking maximum playability and control in a mid-launch and low-spin profile.
FUJIKURA ATMOS Tour Spec Blue 6
The ATMOS Tour Spec Blue is a midweight shaft ideal for medium to high swing speeds seeking a mid-launch to mid-spin profile.
FUJIKURA ATMOS Tour Spec Black 7

Forgiveness - Decent

Sound - Good
Overall - Happy
Upgraded from stage one TM RBZ Driver, no change in distance but may need to optimize the weights and loft. Forgiveness seems better but difficult to tell. I'm overall satisfied and will need to go to the range to toy with settings.
I played in 40 degree weather with wet ground and I was right at if not beating my old Ping G30 on its best day in terms of distance and accuracy. I played in in the +1 degree Draw bias setting, which helped keep my fade a little straighter. I can't wait to get this thing in warm weather to see what it can really do.
In short: This club is an incredible value based on what a driver costs nowadays. Don't waste your money on the high-end models, this club is just as good for a fraction of the price. Cobra has earned themselves a new fan.
