The XCaliber is for those who have got to have the biggest and the baddest. Extremely fast with glide and stability. The XCaliber achieves maximum distance when thrown low, flat, and hard. This is the one for confident bombs in windy conditions. The XCaliber has the stability to let the biggest arms throw with full power. If you have a cannon for an arm, you'll want an XCaliber. Great disc for sidearm throwers and those with lots of power. Can handle headwinds and throws with off axis torque. Definitely not designed for beginning players.
