I had a coworker that ran a 7 sec Mustang, and asked him why he pulled the chute even running 1/8th mile, at Brainerd, which has PLENTY of shutdown, he told me it's simple natural habit for him. He said the people that never pull the chute, are the ones that think it only needs to be pulled in an emergency, but by then it's too late. he also said it's free brakes. Why burn up your expensive brakes, when the chute does a lot of the work? Needless to say, I asked him what chute he recommended? STROUD. Told me you can throw the thing into a ball, and it will still open. His was well abused, and ALWAYS worked.
