New user, long time mechanical keyboard fan.
Been using a matias tactile pro for 7 years or so, which has r3duced keyboard pain and frustration enormously, but I still suffer (mainly from finger pain caused by mousing, I suspect the scrollwheel on my trackball).
Recently got interested in making a split board (key64 / ergodox style), have a couple of donor boards lying about (apple m0116 with orange alps, chicony with inverse futabas).
