I only like to lube worn in Browns and Clears. Don't really use other switch types, so... I use them until they lose that "scratchiness", then lube 'em.
I lube the springs and slider sides with medium to thin lube since it's what I have. I don't lube the legs, although my Browns seem to have some lube there already.
how do the lubed worn in browns feel? my unlubed browns are slowly starting to lose their 'scratchiness' so that's good. is the small tactile bump still noticeable - or does it just feel like a lubed red/linear switch?
Been pressing a few to compare... I'd have to say that the lubing actually helps the bump feel a bit more distinct. Without the "scratchiness" to mask it, the smoother movement allows the bump to be felt more, especially on the upstroke. Overall they feel a little lighter than new Browns, with a slightly more prominent bump. At least that's my "feeling" of them, pressing quite slowly. YMMV, etc.. Again, this is without lubing the legs that press the contacts, just the springs and sides of the slider.
Lubed Browns are my second favourite switch, with lubed 62g Clears being tops. I like the thickest, heaviest caps I can find on both, although they lessen the feel of the bump a bit on lubed Browns. At the moment, I am wearing in the Browns on my KBT Pure and have a set of SP caps on them (Nostalgia set). Once they're worn in and lubed, with a plate installed.... GMK Dolch is going on there.
