The principle of parachute resistance is based more on surface area rather than shape. Engineers tell us that one square foot of chute can lift one pound. Parafoils offer a glide path of about 70 degrees, whereas a round chute offers no glide path...also ribbon chutes can be deployed at up to 600 miles per hour...where a solid chute can be deployed at about 200 miles per hour.
