Oooh did my first full keyboard mod. Completely desoldered all keys and LEDs from my FC700R and put it all back together with stickered/lubed ergo clears and pink LEDs. Took forever, but feels really nice with the original cherry double shots I put on there. I might be regretting not putting a stiffer switch on the spacebar, but I've also been typing on MX Greens mostly lately so I probably just need to adjust.
I got the idea from the_beast to use Super Lube on the springs, and I put just a little bit of sewing machine lube on the sliders. Nice and smooth so far, and I like it considerably better than the browns it used to have. Much easier to feel the tactile bump now.
