I like Realforce boards exactly the way they are and don't feel the need to mod them that much. The build quality on these things really does a good job already in making the board feel quiet enough as it is for me. HHKB on the other hand, amazing board in its own right, but way too loud for night time use, and that's why I can't wait for my silencing rings from KBDFans to get here soon...
I still like a decent scissor switch board, which is why I still have my Logitech K740 that I like to pull out from time to time.
As long as my keyboard doesn't look like a greasy mess, I would not mind having good quality ABS caps.
Even though I'm a light typist, more and more I'm realizing I never liked light linear switches as much as I do with more tactile ones for everyday typing.
