If you remove the springs, click leaves and sliders could it be considered an SKCM mod any more? So, I would definitely stay with just swapping the click leaf. Just for the fun of it, you could try it with click-modded orange or salmon leaves.
On that last point, I wonder if a day will come when someone click-mods SKCM Green )
Haha. I was tempted to do this, but I didn't dare snip a leaf on any of my switches, mainly because they all go to whole keyboards. If they were individual switches, I would have tried it--like Chyros did.
Chyros found that you cannot click mod the switches. It has no effect, likely because of the weird shape of the tactile leaf that's more like a ramp of tactility rather than a very distinct point, so it probably doesn't cause the leaf to really snap backwards at any point. Getting that unique tactile sensation + clickiness is beyond our reach it seems. Well, aside from speaker clickers.
I also tried using SPRiT's lightest springs in SKCM Green and, while it did lighten the force to a degree, it didn't help much. There's not much you can do to lighten the load that SKCM Brown and Green puts on your fingers, I'd say.
Haata described this with how he measured Topre. I forget how he stated it, but it's like... your finger has to do more work--it's constantly battling the force of that ramped curve as opposed to one tactile point, so it puts more force against your fingers. I remember it couldn't be measured simply. It's like work over time or something? Chyros, Hypersphere, or XMIT could probably elucidate on this more than I can.
Being that they're metal and not rubber, that's probably why they feel a significant bit stiffer than Topre.
