All of what Dave said is true, unless you wear a ram-air rectangular

improvement over my Air Force training since that was geared to round
chutes and I now have a much more maneuverable square chute.

Dave, what do you mean by "push, not pull" on chute deployment? Assuming
you're talking about rip cord use, I'd advise pull straight down with
both hands, not straight out.

It has always been and still is called pulling, throwing for main parachutes, but a reserve pull is technically a push. Straight out is best combination of strength and splitting the difference of direction of cable housing. Cables are always from the top on sport gear varies on emergency rigs.
The few glider static lines I've seen clipped to the reserve handle, which isn't ideal but will work. A lot of pilot rigs cannot be reasonably modified to pull the pin from the back.
