Mizuno CLK Fli-Hi Utility wood. New for 2007. Not to be confused with the 2006 model which - very confusingly! - was called the Fli-Hi CLK! Anyway….the Mizuno CLK Fli-Hi is designed for forgiveness, versatility and playability from a variety of lies. This steel headed club has an ultra lightweight titanium crown which helps get the golf ball up in the air and flying high - much easier to hit than traditional long irons.
