The Innova SL or Starfire-L is a fast dependable maximum distance driver that is straight to slightly overstable (less overstable than the Starfire).  It has a long straight flight and excellent glide. This disc can add measurable distance to your drives.  With its quickness, slight high speed turn, long glide and low fade, it will fly a long way.   Easily controllable distance driver with amazing glide and little fade.  The Pro version hotstamp says 'Pro Starfire' altho it is a Starfire-L. 

The Innova Starfire is a fast dependable maximum distance driver  that is slightly overstable (more so than the SL - see below).  It has a long straight flight, amazing glide, a good bit of fade and great control.  Great into headwinds.  A good amount of fade at the end of the flight allows this disc to work well for big S-shots and horking hyzers. 

It is a great choice for maximum distance, headwind drives, a stability driver, control shots with fade, and intermediate to advanced players looking for a consistent distance disc.

Speed 10, Glide 4, Turn 0, Fade 3

"The Starfire is my go-to driver. The width of the rim suits my hand which gives me confidence. I throw the Star Line version because it has perfect stability and is extremely durable." - Valarie Jenkins

"I am a fan of both the Pro (Starfire-L) and the Champion Starfire. The Champion Starfire is overstable even into a headwind and is very reliable. The Pro Starfire(-L) is less stable and has become a very reliable roller once broke in.  When it's new it is an under-stable driver that flies far but I prefer a beatup one for a roller disc." - Kevin McCoy
