I currently use an HHKB (for almost 10 years now) and I love it. But RSI has pushed me towards building my own split ergonomic ortho keyboard. What switches are you currently using on your daily driver mech? I got some 67g Zilents that I'm hoping give me a fairly close feel to my Topres when lubricated.
Having used every tactile from Zilents to Holy Pandas, these are the first switches I'd consider a strict upgrade over the competition (including Topres)
They're crisp, come in silent and unsilenced (I prefer silent), and have uncanny tolerances which results in a consistency Topres can't match.
