The more I look at this, the less I think this is a good idea… the polymer will have weak points around the center disc… I think maybe at best one might achieve an off-center approach… something like this…
That would offer a large re-attachment area and the most stability for the center disc… and it shouldn’t affect performance all that much at all… in fact, prelim testing with me just holding it in place shows no significant difference in performance of either tag.
