I swapped the springs between the spacebar and Print Screen, and it helped quite a bit. I did not, however, swap the stem. Looking at the grey stem, the tactile bump looks similar to the clears. The bump on the grey stem is much more pronounced than the brown, but I am not sure I like it. It seems to get "stuck" on the upstroke, thus making it less responsive. If the grey is anything like the clears, I am not sure if they would be a switch I'd like.
