The Defy is a stable-overstable high speed distance driver.
The Defy is straight with a nice bite of overstability at the end, and is best described as a heavily seasoned MVP Photon or a longer Axiom Crave. Like the Crave the Defy exhibits remarkable resistance to turnover even at high power. Players seeking a long straight power driver will appreciate the line-locking tendencies of the Defy, and throwers not fully powering the Defy will still get a highly useable long overstable disc.
Plastic: High durability for a long consistent life. Designed to withstand the roughest conditions. Transparent candy colors. Also available in soft flexibility for putters. Proton-Line is a Dual-polymer that allows the flight plate core to be manufactured with a different material than the overmold wing. The overmold concept allows the outer wing material to be made with a heavier material than the inside core thereby creating a gyroscopic effect when spin is imparted on the disc, GYRO™ Technology. The gyroscope effect stabilizes the disc's flight and keeps it spinning later in flight to produce straighter, longer, and more accurate results.
