I always hated my Cherry MX 8100’s spacebar for requiring more force than other keys. Turns out it has a Cherry MX Grey switch while other keys have Cherry MX brown switches. I’m going to try to replace it with a brown switch, but I don’t know if I can install a brown switch’s top in this grey switch’s base or I have to re-solder the switch.
Edit: I replaced the switch and it didn’t require re-soldering.
