Well, here's another thing to add to your check-lists...
I usually use closing loops that I fingertrap from gutted 550 cord. I treated the last one with Cypres silicone and it had been going strong for about 60 jumps but was finally showing some fray. So, I decided to throw on the closing loop I got from Jumpshack on my Mirage. It's made from 1000# spectra.
Well, imagine my surprise when I pulled the cover flap back and saw the bottom of my closing loop. The washer that keeps the knot from slipping through the grommet on the container flap had sawed through about 70-75% of the closing loop!
It was a premie/horseshoe just waiting to happen. I was able to put a rod through the loop and snap it with a few sharp tugs.
I checked both the grommet and the washer and there are no burrs or nicked edges. It was simply the thin washer slicing the cord over time.
I'm not using the washer with the spectra loop as it's thick enough that the knot isn't going to go through the grommet, but those of you who have been using your loops awhile definitely need to check this one out.
