To secure the shade more participants are using what I call the flying saucer shape with at least 1 strong mast and 6 poles with a cable /rope running all around the chute connecting its guylines.
Same flying saucer shape with 14 pvc poles without the all-around cable/rope.
This Ribbon-ring parachute will let the air flow through.
It's always better to give an aerodynamical to your parachute shade.
From a distance it looked like a Georges Rousse installation
