Blind Spots - STOP Turning! 

Head on a swivel does not work. We are not owls, our shoulders are locked in place by the rig and we have huge blind spots below and behind us. Any turn over 90 will put you into your blind spot, going fast. We also have huge blind spots above and behind us, where the danger may be coming from.

The only way to minimize collision risks is to minimize turns. The standard of excellence in skydiving should be how little control input you use from deployment to landing. In the big picture, our culture of making unnecessary turns is even more of a problem than aggressive downsizing.
