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'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.
I think all the ergonomic keyboards assume you use the opposite hand for the shift key.
