This is what Prodigy says about the D-1: The D1 is a very fast, over stable driver designed for power throwers. This driver is good for all conditions and flies as well into the wind as it does with the wind. The consistent flight path of this disc makes it a favorite of disc golfers looking not only for a long flight but pinpoint accuracy. The flight path is similar regardless of the weight.

According to Prodigy, these Yellow D-1's are slightly less over-stable than the previously released Blue ones, in order to achieve more distance.All of these discs have been weighed by Disc Golf World.
