The FD is a controllable low-speed driver. Once you learn its magic you'll never leave it out of your bag. Packed with gigantic glide, this bad boy is also sneaky long if thrown accordingly. The FD is at its best when you need to make an accurate drive and land smoothly on the fairway. Factory Seconds are cosmetically flawed discs that did not meet our quality standards for regular production. The flaws do not effect flight characteristics or durability of the disc.
