Yea I tried O-Rings on a brown switch and it feels very bad in my opinion. Just feels very mushy.
Nice vid btw.
Just out of curiosity, are topres same as rubber domes when it comes to activation point? I mean MX Cherry switches activate when pressed @ 2mm. Is it the same or...?
You pretty much bottom out Topre switches. They get to a certain point and then they collapse completely. The whole action is a lot smoother and less jarring than a rubber dome membrane board though.
You can register a keypress without completely bottoming out but it would require pretty deliberate effort and I doubt you'd notice much difference in feel by purposely attempting not to bottom out.
Edit: 30g uniform would be your best bet at achieving the feeling of a Cherry brown as tactility on 30g is very faint
