High Speed Max Distance Driver, the sticker on the back say this is a prototype Firestorm, the manufacturer also marked the FST designation and it is not embossed on the disc as newer Innova discs are. Red Happy Holidays foil stamp.
Description from Innova website:
The Firestorm is a wide-rimmed, speed 14 distance driver that some would describe as a faster, beat-in Destroyer. On low, level drives thrown with enough speed, the Firestorm flies straight with a forward-finishing fade.
