I have HHKB Pro2, and now gonna buy HHKB Pro2 Type-S, but in my opinion, HHKB it's not the best options for you
the better point in Topre with CherryMX IS Topre never get double click, and CherryMX do, but if you press to keyboard too fast then the HHKB won't recieve that button, but that speed it's not easy to reach so
HHKB Still are one of my best choice til now (and make your own custom, HHKB is the final gate to you to come to custom keyboard)
