I chose to learn Colemak-DH [0]. Before learning I was around a 75-80 WPM Qwerty touch typist. I went all in and did a lot of heavy practice. It took me around a week to be able to touch type colemak-dh (slowly) and then a further few months to touch type at speed.
I didn't want to lose my ability to use Qwerty so after getting up to a moderate speed of ~45 WPM I exclusively brought my colemak flashed happy hacking keyboard to work, and left qwerty at home. I have now equalized at about 60 WPM on both layouts after 8 months, and can pretty easily swap between them.
Now I don't really know what to do, nor have I noticed really any perceived benefit of switching layouts. The biggest difficulty has been vim keybinds. I really don't want to have to remap all of my vim keybinds (as like the OP article states, I think of my vim commands based on their name and qwerty representation) so I have been relying on multiple keyboard layers to handle movement keys and the like. Having to use modifiers, remember the different locations between layouts, and stealing away previous CTRL+<key> modifiers from vim to accommodate this kind of sucks.
I notice no difference in wrist (dis)comfort, it's just become more mental overhead to typing, and I am kind of stuck. I guess I am waiting to have some time to think about what I want to do, but balancing two layouts doesn't seem practical, or reasonable, or efficient.
