I am currently running the regular crystal with Cherry Silent Reds and some Aliaz Silent Tactile and with most of the keys being Holy Pandas. I have been running the brass plate with the idea of installing the "plexi" plate soon.

One question to raise is if an owner would "dye" or varnish the brass plate. "As to how many a person owns."
I'm sure Isaac Asimov would be proud of the RGB. "Which you can turn off!"
