I have used a design similar to your chunk holder for plastic trailers on weedless spoons. I loop the wire over the hook and twist it a half dozen times (like a bread bag twist-tie) and bend a little hook on each end of the wire (at slightly different lengths), then just push it into the trailer and you can fish all day without it coming off... (of course, if ol' razor mouth chomps on it, that becomes a different story).
