Which ergonomic model did you choose?
I’m now a happy user of the kinesis advantage (though the configuration software pales in comparison to the ergodox) and feel so much better.
I modded all of the 2s with the following boards:
* https://github.com/kinx-project/kint - Great board, requires usb of course. Programmable with QMK.
* https://github.com/wizarddata/Blue-Wizard-Mod - Doesn't support QMK but does support ZMK but is bluetooth. Great board.
I picked the kint up on some pcbway type service, the blue wizard I got off ebay.
I think all the ergonomic keyboards assume you use the opposite hand for the shift key.
I've been on advantages for 20+ years at this point and haven't had any of the RSI that prompted the switch since.
Currently daily on a 360pro. Might want to sell it or reswitch it for something a little lighter and maybe even something linear. Maybe a silent red or lf red.
My guess is that, for most people, myself included, once one has invested the time in learning any particular ergonomic keyboard (Ultimate Hacking Keyboard, Ergodox, whatever), the switching costs are annoying that one just keeps using it
A small number of people seem to get obsessed with the narcissism of small differences in terms of switches, or minute aspects of positioning, or similar matters, but I find that one hits diminishing returns quickly and it's less the keyboard than what's done with it.
