Think about your reserve and the system it uses.
The lines are stowed very much in the same way as some of the newer 'd-bags' in circulation. They are still in an experimental stage, but it stands to reason that more people will end up using this system, if only because they have seen it and want it!!!
The thought behind it is that the lines reach line-stretch without the d-bag oscillating side to side due to line bights having to overcome the tension of rubber bands. This, in theory, helps prevent line-twist
and provides for an increased probability of an on- heading opening.
For reserves it also means less forces to overcome in order to provide a rapid deployment of the canopy!!! In a sense you could call it line dump, but far more important is the line tension within the canopy as it is folded and placed into the bag. The tension should be proportional to the line attachment points and the overall exposure to the wind stream the canopy is exposed to during deployment. In theory.
Then shit happens and you start at the beginning.
In other words, if you pack and place your canopy into the d-bag with slack lines, brace your self. It is about creating a load path without slack. The same can be said for lines that have been stowed assymetrically between the left and right side of the Main Lift Web, or your risers not being even during deployment.
Does any of this make sense?
