So the Type-S sliders are identical to regular HHKB sliders?
Why the hell did I pay the extra $40 for a Type-S then?
well, it'd cost about the same for hypersphere rings for the same effect, but you don't get the sweet Type S logo with those (though you can buy some type-s/colored hhkb logo stickers from korea i think), so it's not a bad buy if you only pay $40 more. the issue has always been that EK charges like $100 more for the Type-S, which is total horse****.
here's the pfu specsheet for reference. the missing 0.2mm implies the sliders are the same to me, but maybe that same amount of travel distance is lost on the longer purple sliders too and it's just so negligible that you don't notice it.
