I enjoy a bit smaller boards. 60% is the sweet spot for me.
For me using wrist rests with small boards feels very counter intuitive as it kinda negates the benefits of smaller footprint.
My keyboards also do not have angle. Why would you have an angle and then add something to kinda mitigate it a bit?
Since getting a vertical mouse and using only 0% board with proper ergonomics (desk height, screen height, chair height etc. ) I have had zero wrist pain.
I just wish there were more options for 0 / negative adjustable boards. Currently the options are mostly self soldered pcb or some rare gb-boards.
