D2 is a very fast, over stable driver that is designed for strong throwers. Just slightly less stable than D1 this driver is good in all conditions and flies just as well into the wind as it does with the wind. It is an extremely reliable driver with the least amount of side-to-side movement of any driver on the market. It is equally as long, twice as forgiving and has a much gentler finish.
X-Outs or Factory Seconds are discs that may have cosmetic blemishes, stamp drop outs, or other reasons the disc was classified this way. Flight is not affected. These are a great way to try out new plastic at a more affordable price.
