DSA profile is flat, so since the rows are interchangable (except if there's a colour difference, or a homing key) I think you have a few unnecessary keys here.
- The base kit has an extra Up, Up, Dn, Dn, and a 1.5u \. The key left of 1 should be `~. I'm then unsure what the paler orange End is for.
- The orth kit has an extra 1u Tab, Up, Dn, '". Possibly it would benefit from an extra 1u Shift, Ctrl, Alt, Fn, for ergo/orth boards with two of each modifier, although I wouldn't personally use these.
- The numpad kit has an extra End, Dn, -. Maybe a "Back" would be appropriate.
(I'm possibly interested, but only possibly.)
