read this it will tell you about how to adjust (bend) a epic to take on different flight paths.
this applys to all discs.
i have a buddy that makes his boss less stable by doing this.
by bending and tweaking the disc you can make it so the epic does different flight patterns after it flips on a thumber and then flies flat way up in the air.
sometimes you want to hyser after it flips sometimes you want it to s curve.
ive seen this disc flip 3 times with a thumber.
