So, just for anyone who happens upon this thread, I ended up going with Gateron black stems in stock Cherry MX black housing with stock black springs. Lubed the housings and stems up real good, and the result is pretty fantastic. Deep, muted down and upstrokes, super smooth all the way through. It was worth all the effort.
On a different note, something is up with my spacebar stabilizer (Cherry). One side is not coming up as high as the other, which is causing the spacebar to sit slightly crooked and bottom out differently on the left and right sides. Anyone ever experience this and/or have any suggestions for fixes that don't involve entirely desoldering the board again to reset the stab
?
