Was bored at work and saw
http://geekhack.org/showwiki.php?title=Island:16351 by mtl about modding his Filco to Cherry Clears.
He mentioned at one stage that the black springs were actually lighter than the clears:
It may not seem obvious that black springs are weaker than clear springs, after all, black switches require higher activation force than clears (60 cN vs. 55 cN). I think this can be explained by looking at the tail end of the force graphs. The black spring actually bottoms out at about 80 cN, whereas the clear spring bottoms out close to 100 cN. It helps to look at the force graphs overlaid:

By combining the black spring with the clear stem, the result is a key switch that's easier to press than a Cherry clear, and more tactile than a Cherry brown. It finds a really nice sweet spot in between, and is my new favorite key switch! Since it's a cross between clears and browns, I think the name "ergo clear" fits well.
I was under the impression that Ergo Clears were Brown spring, Clear stem.Regardless, it got me thinking. What would a Cherry board feel like if you made one like this?

The entire board being Clear stems, but the white areas being with Black springs and the green areas being with Blue/Brown/Red springs.
Has anybody tried something like this? I'd like to know the result as I've got two Deck BL83s (Blacks) and one Cherry MX8100 (Clears) on the way, and already have a KBC Poker (Browns) in my possession ready for a bit of tweaking. I'm too cheap to get a HHKB or the like - I'll end up selling most, if not all of the leftover gear.
