The Spy is a putt and approach disc rated 4/3/0/3. Zero turn and a 3 fade on a slow frame suggest an approach disc that flies straight for a beat and then works left for a right-hand backhand, with little glide to carry it past the target. Northstar's distributor listing keeps the pitch short, calling it an approach disc extraordinaire that arrives board-flat and ready to go, and its flight figures match the ones carried here. TryDiscs records Base-Line, C-Line (Northstar) and NS-Line runs, a three-plastic spread that, among Northstar molds on this site, only the brand's Pacific OS and Zoom match as of 2026. PDGA approval came on 27 June 2022, in the Danish brand's five-mold batch.
