I vaguely remember discussing it with Steve (of Rockhardware) at some stage in the not so distant past while standing in the pines. They weren't happy with the threaded bolts on Thin Edge of the Wedgie among others and were discussing replacing them. I do not know if they have got around to doing anything but that's the first place I'd check.
