Some comments on the ergo kit.
First let me say that i understand that this is an SA profile which will not lend itself to the flexibility of a KAT kit, but a fair amount of research has been done recently into what the key layout of an ergo KAT kit should be.
Now my notes on this ergo kit.
1. it may need some extra R3 1.5u keys. As it is, if you are a user of a boardwalk, sol, zen, mun (or a few other boards i can't think of right now), you will have to use all 4 of the R3 1.5u mods as the bottom row of those boards has 1.5u corners.
2. doesn't the alphas kit come with a 1.5u pipe/backslash key? that shouldn't have to be in this kit.
3. an r1 1.5u tilde key would be a nice addition for those of us who DON'T put escape on the top row. (I believe it is becoming more common to move it from there)
4. an r3 1.5u enter key would also be very welcome as a number of people replace the quote key with enter. and some people (like me, put enter on the bottom row)
5. an r3 1.5u function/layer key is VERY common in place of caps lock. (personally i use escape on r3 but i overload it with a layer so function works for me)
You should at least take a look at the KAT ergo guide (
https://geekhack.org/index.php?topic=105714.0) put together by NoPunIn10Did. He did a lot of research on ergo layouts for that guide.
Another note is that on a number of ergo boards (that are NOT the ergodox) the center columns can be 4 1u keys instead of a 1u and 2x 1.5u vertical keys. I'd love to see that considered here, but i get it if that's just too many keys, I almost never have those columns in the right profile anyway and they vary a LOT with personal preference.
As for what would make this an ideal ergo set for ME (i use an RGBKB sol and RGBKB sol2):
* add r1 1.5u tilde key (my upper left 1.5u)
* remove r2 1.5u backslash/pipe key
* add r3 1.5u escape key (function or layer would do in a pinch)
* add r3 1.5u enter key (my bottom right corner is enter.)
* add an extra r3 1u alt key (i have 2 in my bottom row)
* add an r3 1u delete key (i have one on my bottom row)
* add an r3 blank or 2 for really bizarre layouts (my bottom row has an extra .> key which i don't expect ANY keyset to match)
and in my DREAM set, there would be an R1 1u print screen, R2 1u F5 key, R2 1u pause/break key, R3 Insert key, and R4 delete key, in addition to the notes from above.
I'm not sure about usage of the upper keys on the thumb cluster of an ergodox as i haven't used one, but is it common for the thumb clusters to BOTH have ctrl and alt? Also, does the top row of those clusters need to be R2? If it was R3 there would be a lot more flexibility in the kit.
If you've read this far I'd also like to say that since before i got my first keyset, SA Carbon has been one of the sets that interested me the most, and i've always particularly liked how it looks on ergo boards.
Thanks for reading my ramblings.
