The MD3 holds lines very well, so whether you are going for a hyzer or anhyzer shot, it holds the angle very well throughout the flight. Straight shots stay straight also if given enough power. Factory Seconds give you the opportunity to purchase blemished discs at a discounted price. 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. The flaws can be one or more of the following: misprinted stamp, bubbles in the rim, or specks in the material. Factory Second orders are subject to availability.
