Here's another knot to think about.
I still prefer the Duncan UniKnot for tying the shock cord to the nose cone eyelet or screw eye.
With the Duncan Knot, the tail ends of the shock cord end up facing down, side by side. The loose tail doesn't stick out.
This cinch style knot (shown above) has the loose end of the cord facing out and might get caught up between the nose cone shoulder and body tube.
