S-Line is Discmania’s grippy premium plastic. It was Innova Star under a Discmania stamp before 2021, and Discmania has moulded it in-house since. Opaque with a little translucence, and the choice when C-Line feels too slick.
That makes it the all-weather plastic in the main Discmania range. It holds flight for a long time without the glassy surface, and it keeps grip when wet. Fourteen moulds are listed in it, and Horizon is an S-Line run with a white-and-colour swirl.
It isn’t quite as durable as C-Line, and it beats in a little faster. That’s the trade you make for the grip.
