I'm starting to thing I need to dive in an make myself a bridge hammock. I've been reading some of the tutorials and posts and spectra seems to be very popular for suspension. My question is why?

I have some of the 2.8mm spyderline from west marine, I know it has a stiff hand and really holds knots. Where as my single braid dyneema is a little limper and kind of slick. I'm guessing vectran would be even more so but haven't handled any to know first hand.

Of course having purchased both of these I also know how much less expensive the spyderline is and any of the dyneema single braids.

So the question is, does spectra enjoy the popularity it does because of its physical properties or its price?
