The Basileus Biz90 Graphite Iron Shaft was designed with the faster swinger wanting a good combination of soft feel and accuracy. It features a premium high modulus material design that helps create a very consistent and soft feel with each shot. The Biz90 features a precisely calculated flex characteristic where the flex point is made to be exactly in the center of each shaft which helps produce a strong mid trajectory. Basileus has utilized a new boron material weave that wraps the shaft to create enhanced feel and stability, even at high swing speeds. This design has allowed the shaft to achieve a predictable flight without any ballooning for the ball.
