Something like this? The heavy stagger is great, 42 keys is almost perfect, but the thumb placement is -- for me -- horrible. Having to move my thumb to practically under my palm is just terrible ergonomics.
This thumb layout reminds me more of the ErgoDox variants, and is far better placement. Is there a layout close to this?
Oooo, that's better! It's a few keys short, for me; I need those missing 6. I'm already past my chording comfort level. Maybe a little more pinky stagger, too, but this would probably work.
