Innova Invader. Cheap price fast shipping in the US. Innova says this about the Invader: The Invader should be your approach workhorse. It is the ideal Putt & Approach disc for full powered throws both backhand and sidearm. It features a flat-top and small bead that creates a comfortable in-hand feel. The flatter top profile also reduces errant glide, allowing the player to power the disc to the correct distance for more control. Invade the circle from the fairway or the tee.
