King F9

For the first time in a Cobra fairway, the ultimate precision of CNC milling is combined with SPEEDBACK™ and BAFFLER® Technologies to deliver our longest, fastest and most accurate fairways. E9 Technology is a variable thickness structure designed in an elliptical shape (along 9 different points) that expands the SWEET ZONE accross a typical miss-hit pattern that ranges from the low heel to high toe areas. We tested two different versions of the SPEEDBACK fairway - one with a CNC milled face and one with a hand-polished face. Results with the CNC milled face showed ball speed gains up to 2.5 mph, which translates to over 7 yards!
