The illustrated disc flight line is based on the manufacturer field testing results, during its development process. So, to level the playing field we chose to put a different spin on things for such visual illustrations. Sticking to the manufacturer's test results will offer you a good baseline for how that particular disc will fly.
The Innova Champion Firebird Disc Golf Distance Driver is a control disc. It's not designed for distance but to be an overstable disc that you can rely on in strong wind, and can be thrown forehand, backhand, or overhand with equal use.
The flight path of the Firebird depends on how hard you throw it. It's a 9 speed that you can throw as hard as you want. When thrown with lots of power it can fly straight for a time before hyzering out. If you throw it on an anhyzer it will be a flex shot. And if you release it on hyzer then it will hyzer the whole time before skipping. It has a wide rim which makes it ideal for skip shots. The Firebird is a utility disc that leads to some great and interesting shots. It's the disc that helped Nate Sexton become the 2017 USDGC champion. It's a disc beloved by 12x World Champion Ken Clim. It holds as much power as you put into it. You won't flip this disc with a strong backhand or forehand, even into ripping headwinds.
Champion plastic is Innova's most durable plastic. It's the most overstable right out of the box and it's going to maintain that flight path for a long time. It's a little smoother than star plastic and will take longer to beat in. It's typically on the heavier side 165-175g, but you're using it for control not distance so a heavier disc is better for that.
It's a utility disc that pros love, amateurs use constantly, and it's something you'll find yourself using any time you're in a tough situation. The Innova Champion Firebird is an exceptional flat top disc that you'll love.
