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 Discraft Z Line Force Disc Golf Distance Driver is a very overstable disc with high glide. It's meant to handle all of your power and not flip over in any headwind situation.
The flight path of the Discraft Force is straight for about 50% of the flight and then it begins with a long slow hyzer with lots of glide. This disc is like a longer overstable control driver, with a dome top for lots of extra glide. It's got a wide rim and can take a forehand or backhand at max power without flipping, even from pros like 5x World Champion Paul McBeth who throws the Force regularly. It's definitely for advanced players with bigger arms who are looking for more control than distance. Experienced players will learn how much fade happens with their Force and can plan for that reliable fade. It's a special disc that you can crush on time and time again. After it beats in it will just fly longer, but maintain that overstable finish that was intended.
Z Plastic from Discraft is their most stable plastic and their most durable one as well. It's perfect for the Force because you're throwing this disc with power and you may occasionally clip a tree. It won't matter though as it's going to not pick up nicks and gouges, and will retain that overstable flight path for years to come.
The Force was built for controlling your throw and to handle powerful shots. It's not your furthest flyer, but if you prefer knowing where your disc will land every time and getting some distance. The Force should be your choice.
