Why is Kevlar cord the way to go for attaching the shock cord to? It's obviously lightweight and strong, but also seems thin, which makes me believe that it would cut through the shock cord when under stress. I've used thin paracord, which is many times thicker than kevlar, but doesn't seem like it would cause the shock cord any damage. I'm doing a build now which includes kevlar line, I'll be interested to see how it performs.
Another question I have, is that looking at HPR videos on youtube, everyone's shock cord is about a mile long. Are the ejection charges that powerful? Or is there some other reason that you need to pack that much into a small diameter tube?
