Nowhere near as good as I thought it was going to be. I think the stem mechanism of the blue switch doesn't really work out well with the clear spring. It feels like it requires much more force to actuate than a stock clear.
I've been doing the somewhat crude nickel test on various MXs. Since I've been experimenting with putting blue springs in clears, I happened to have some disassembled blues and clear springs lying around. So I threw one together and tested it.
For reference, here is what I had previously found:
11 nickels - stock blue
12 nickels - ergo clear
14 nickels - stock clear
Given that, I expected the clear blue to be somewhere in the range of 13 to 15. (Greens are 15). The actual result is: 17! That's higher than the white at 16.
Your fingers seem to be telling the truth. That's the highest activation force I've seen yet.
