You want to make sure you rig has a D Ring Reserve Handle.  Metal D rings don’t have the snag hazards of a soft pillow.  The pillow handles have a firm top shelf that makes them more easily snagged and removed when you least want them removed.  Also, make sure you have a good reserve flap with good tuck tabs that isn't easily opened.  AADs are certainly ok but make sure you disconnect your RSL.  In the event of a cutaway, we are going to want to gain as much separation vertically and horizontally as we can safely gain.
