The Elite Z Avenger™ is a maximum distance driver with stability ratings of 1.6 to 1.8 (moderately overstable).  It can be used by amatuers and pros alike. It can hold a line in the wind. You can throw it anhyzer and it will slowly fade back to a hyzer. Throw it flat and it holds a super straight, extra long flight line. It is a great choice for controlled distance. Great for hard pulls and windy conditions. It helped Nate Doss win the 2005 Pro World Championships.
