Yeah, that’d be me. Switched to a Moonlander first to manage an RSI, went cold turkey to Colemak too. As someone else said, I wouldn’t recommend switching layouts. I like it, but I don’t necessarily think it’s worth it.
I think the split + tenting definitely helps. Actually, scratch that: I know, because whenever I switch back to my Apple keyboards the ulnar deviation pain is obvious. But I think the fact that the switch slowed me down SIGNIFICANTLY helped, too.
I’m deep in the rabbit hole now, though, on a Corne, as I found besides ulnar deviation, right pinkie overload was the next cause of pain. And wrist rest use (turns out you’re not supposed to use those for typing, just for resting, but no one tells you until it’s too late).
So yeah, lots of factors, you have to honestly assess yours and address them. It’s not a straight line, you kind of have to try and see what works for you.
Yeah, I’ve hit some of that. Placed some relatively “less used” keys there.
