FWIW, I've not had a real failure with dynaglide when done "properly" as well. But as I say that I do have to admit I don't bury my cords as deep as some here say you need to.
I did have one eye pull out while on the trail when I only did it about 1.5" in and did use a lock brummel or back stitch - which in hind-site is totally stupid to not use at least one.
I now use about 2" of burry and .25" of taper on dynaglide and always stitch lock it in. I've read that this is only about half what you are supposed to need. But 2 years with that sort of rig has never let me down.
