So you need enough lines of your chosen shock cord to give you the "pull" you need. I actually went to the bother of measuring and drawing up graphs of how much pull the shock cord gave at 10 - 100% elongation to get an idea of what was available from the cord. I suspect that it is always going to be a balancing act of weight and performance (as is everything we build).
I think the most important point that I have found, is that the potential weight saving are in the attachment points, not the cords ... dropping the size of the materials used to attach the suspension has far more weight savings possibilities than the cords themselves IMO.
The above photos use 3/4" grosgrain and 3/4" split rings ... the newer suspension I just finished uses 1/2" split rings and 1/4" grosgrain loops attached to a 1/2" grosgrain base ... much lighter and likely still overkill for purpose.
