Huh?? I get a nice CLICK at half way down on my mech boards. Even the Cherry reds activate at halfway. Once I get the feel for where 2mm is, I no longer have to hammer down hard to ensure a good key press. I prefer the clicky keys for the feedback though, even though I am getting a feel for where that point is.
With rubbers, I have to hammer HARD, and all the way down. If I don't bottom out I don't know whether or not I'm succeeding.
