Ozone Delta 4 vs. Flow Fusion light - Glide comparison

We went for a fun glide from Kobala takeoff to camp Gabrje, after Naviter open task. Unfortunately my friends accelerator is not working that time, so we just flew down at trim speed. As you can see, the 2 gliders fly identical in these conditions. Delta 4 xl loaded at 125 kg (certified max 130), Fusion Light L at 109 kg (max 115).
