The Scorpius is Millennium's Destroyer-based long stable driver. With a long glidey flight just shy of neutral-stable and a dependable fade, the Scorpius is one of the longest control drivers we've ever tested. Throw it hard enough and it will give a little flip, riding out until a very late forward-penetrating fade.
Millennium's Sirius plastic is a high-end blend that resembles Innova's Star plastic. Sirius plastic has added grip to help you hold on to the disc, and is also super durable to retain original flight characteristics for a long time.
