Have you tried or were inspired by The Voyager? My friend has a Moonlander and we were discussing that the Voyager might be the ideal for the setup we were looking for.
My first split was a corne (I have a feeling that many people started with a corne here) and then I wanted a draculad[0], but it wasn't available for almost a year. These two keyboards had given the most of the inspiration for the YetiS.
