I've switched ours on the Camplet; not glow in the dark, but high visibility and lineloks. I would recommend them, they are really secure and really easy to use.
What I have (mishmash of old and new guylines, various types of sliders) at the moment seems to work perfectly well so I'm in no hurry to swap them. Why fix it if it ain't broken? I do have to replace guylines now and again though and when that happens I'll consider linklocs. It's more likely to be what I have rolling around in the bottom of the spares box though.
