MX Brown (minor tactile bump), MX Red (linear), and/or Topre (capacitive rubber dome, comes in different force varieties) might be to your taste if black ALPS is too stiff for your tastes.
I like tactility, so I favor buckling springs, MX Clears, and MX Blues, but I don't suffer from carpal tunnel syndrome or RSI, either.
Since you also seem to like the slight tactility that the black ALPS switch offers, MX Brown seems like a safe bet, and it's fairly common and relatively inexpensive, too.
