Adjusting the choke is very important! Use the provided red or black shrink wrap as the choke. The choke needs to be adjusted based on how you want the parachute to function; if you want to use the chute on nearly every run as an aid to slowing down, bring the choke along the strings to nearly the end of the parachute, leaving just 3-4" of string exposed before the parachute begins.
