So what keyboards are being made with clear cherries?
A lot of cherry made boards in Europe, just the Deck legend tactile in the US. If you are in the US you can find a lot o of Cherry POS boards sold on ebay, usually they are also programmable.
I haven't read anything about ergo clears but I clickyness is something I am after.
Look at the cherry wiki in the wiki section, you can't buy an ergo clears board. You need a clear one plus a brown/blue/red board to swap the springs (on pcb mounted boards this is feasible w/o any soldering, like on alps.
The same applies to tactoblacks, you need a black donor board.
Should I suck it up and just go with browns?
I can't suggest that route, browns are switches w/o any personality, they are insipid.
Are usually the first choice for newcomers, a person used to alps can be only deluded by them.
What exactly is meant by hysteresis? I read a bit about it but perhaps you can clarify for me.
The point when the switch actuates (pushing the key) is usually different from the point when the contact is opened (releasing the key) especially on tactile switches.
Also alps are affected. but while those points are relatively close on Alps, and cherry brown, clears (and derivatives), on blues those points are relatively distant.
A blue switch, once actuated, needs to be released almost completely to start a new cycle, so they are not good for dublle tapping and for fast tiny corrections you talked above.
