Ya, I would be interested in the bolt stabs as well. Mainly because I have never seen them before, so that makes me want to try them. Oh and because pcb mount stabs always come out on me when I pull tight keycaps, which is annoying...
My interest in this GB stems from exactly the same problem. When I built my TrikX I used the stabs and wires that Team Redline include with the PCB, Case, etc. To be fair, they included way more wires than I needed but now I'm thinking it's because they were manufactured by a third party (the wires, at least, if not the Stabs also).
Most of them are working very well (and they are much, much better than the Plate Mounts that came on my Leopold .. my first mech... back when EK first swapped over from Filco) with one exception: my numpad zero: the wire on that stab always pops out when I pull that key off. Fortunately, I've settled on my favorite colorway (WoB) and they have stayed put from some time. Also fortunately, this stab wire has to be the best stab wire to have this problem with: I can just take the PCB and that stab wire is right down there are the edge of the board and I can pop it back in with precision screwdriver.
That said... I am hoping that my problem is merely that the OD of the stab wires that Trik provided is (however slightly) too small and that swapping this out with a (hopefully) closer-to-spec stab wire from Cherry sorts this all out.
Cheers,
