Ozone Zeolite GT MS — A Light D-Class Two-Liner with Great B Handles

The choice comes down to weight versus movement in rough air. At 3.5kg the Zeolite GT is light and sits above the M7 on performance, but in strong, turbulent air it moves all the time and the pilot has to keep holding it overhead with the brakes. It suits a D pilot who is already comfortable flying that way and wants to cut weight. If a wing that moves less in rough conditions matters more, the heavier Zeno is the better choice.
