Hey OOTA, are you using the SS switch or the Brass? I find the brass to be much smoother than the SS but am making myself use the SS now to break it in. Cutting down the spring makes it so much nicer to use but the crunchy feel just takes a while to wear off (manufacturing specs on these Temon switches are pretty close so they feel pretty tight when new). I'm half tempted to do a couple twists of the button shaft with steel wool or super fine sandpaper, just don't have any desire to tackle that c-clip again till absolutely necessary (proverbial thorn in the Lion's paw...).
I'm using the SS switch. It's much better with the spring cut down, but it's still tight. I have another 14*** mod from another maker in Greece and the switch is sublime, it spoiled me.
