My thoughts on reserves.
In my youth i did a lot of skydiving including CRW. Canopy Relative Work where canopies are stacked together and ended up a few times getting into situations where my main parachute had become entangled and have to cut away the main and go onto a reserve parachute.
I have seen partially collapsed square parachutes start spinning, the inflated part overtaking the collapsed part. If you deploy a steerable reserve in this situation it can start reacting against the wing and not fly as it should.
I would recommend a round reserve so at least you would come down at a safe rate and not under two steerable wings that are flying against each other.
I know that skydving canopies and paramotor wings are different but its one to think about.
