The Halo Teebird3 should be the gold standard for all Fairway Drivers. The Teebird3 combines modern technology with classic flight characteristics you know and love. Added torque resistance and the flat top make this an ideal disc for backhand or forehand throws. Halo gives you all the looks and the Teebird3 will get you all the birdies. Factory Seconds are cosmetically flawed discs that did not meet our quality standards for regular production. The flaws do not affect flight characteristics or durability of the disc.
