I have some old Cherry Whites - factory-lubed Greens, ie heavy lubed Blues. I like them - the lube seems to take out some of the treble in the sound and makes the click feel softer, particularly at the beginning as the collar starts to engage. The only trouble is, with use mine have deteriorated in feel - but then, they've never been re-lubed. Modern lubricants might well last better.

I don't know if there are any other factory-lubed clickies - much of the attention in boutique switches seems to have gone towards replicating the Alps click feel (which isn't my preference). I also wonder if we could get closer to the Model M feel - perhaps using a conical or multi-stage spring.
