Yes, I may need to go that route. Would some spyderline be extremely non stretch? If not, what cord would be extremely non-stretch with minimal weight? I have no idea what the thin black cord is that makes up my stock ridge-line, but it does sound like I can stretch it.
I've been thiking about getting some of those tarp ad on doo-dads that someone mentioned ( Slowhike?). Can't think what they are called. One on the bug net, one on the underside of the tarp, thin cord connecting them to pull the bug net away.
