I've built about 10 mechanical keyboards so far, including a bunch of split ergo ones and low profile variants too. From that, I know the layout matters a lot, as well as the switches themselves; the programability and other features to me are nice but ultimately can be worked around.

I'm curious about the switches you're using. On the tech specs it says: "Dual steel arm scissor switch w/ retention spring, 40gf actuation force"

Are they custom switches then? If so, are they most similar to current Magic Keyboard switch feel, or something Choc or MX low profile, or their own thing altogether?
