Now that I've had some coffee and am paying better attention, C., I realize you're saying this is something that's supposed to occur from use, correct? Not a spontaneous degradation of the ring material? In that case, I doubt it would apply to my FK-6000, which was NIB, and which I've used only occasionally. (I wouldn't want to enjoy it
too often, since people have made it so clear here on GH that Futabas aren't supposed to be enjoyable, LOL.)
People are always searching GH for advice and tips, though—so if you do find that DT topic again, I'm sure some of them would appreciate it if you'd link to it here.
BTW, has anyone ever bothered to lube Futabas? I couldn't find references to that here or on DT. Wouldn't it be funny if lubed clicky Futabas turned out to be as good as, say,
Alps Blues, prompting a mad rush for Futaba boards before their prices skyrocketed? Seems unlikely—but considering that some people are glad to pay hundreds of bucks for a single key cap, it seems like anything's possible in the world of KB mania.
