The Sirius ES1 Prototype is the first release in Millenium's "Experimental Series." It's a distance driver designed for ease of throwing and smooth S-Curve lines. Rated as 11/5/-2/2, its combination of glide and -2 high speed turn enables slower arms and intermediate players to throw long range flex shots. It's also big-arm-friendly with its blunt wing and low speed fade that bring this disc back with a reliable fade after its mid-flight drift. Players of all skill levels will be able to find their flex with this disc and help carve fairways with tight, long-panning lines.

Sirius is a premium plastic with the ultimate combination of superior grip and die-hard durability; long lasting and a nice grippy feel in opaque colors.
