Discs are designed to fly differently. Some fly straight. Some don’t. For those that don’t, they follow all sorts of different trajectories—knowing how each disc in your bag flies is critical to being able to weave your way through a course dodging trees, avoiding hazards and snaking around bends.

Check out the resource from our friends at Discmania to learn more about how the different numbers, different plastics and different shapes all impact the trajectory of a disc.
