Here's what Innova has to say about the XCaliber:
The XCaliber is 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. 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.
