SA is a horrible profile I can't for the life of me understand why everyone wants everything SA.. and I totally agree this set doesn't work as SA it needs to be either cherry profile are DSA. I wouldn't mind maybe seeing this run as a JTK set to help with cost perhaps? Are perhaps just running it thought the original manufacture? I would think if they did that dies would exist already.
DCS is horrible - I have to say first - for the fact that their cap thickness is like paper-thin.
I have DCS, DSA, SA, GMK, JTK, EnjoyPBT PBT, POM at home, and DCS can serve me for decoration purpose, i.e. good for the numeric row and above. It feel horrible to type on these super thin DCS caps.
In terms of thickness and feel of typing, let's set aside the profile of caps at the moment, then I will rank:
POM = PBT > GMK = JTK >= SA >> DSA >>> DCSI agree with some of your points:
1. JTK Bred has a similar color theme, but I am not sure how willing and what is the MOQ for JTK to have custom caps like here.
If JTK can make custom decoration sets for this set, I am both hands and both feet up to support.
2. The SA profile follows / was inspired by the heritage of IBM Selectric Typewriter key cap profile in the 1960s and 70s. For sure the profile is a bit outdated as people do touch type and do not whole arm movement as much during typing compared to the old days. However, SA is still quite usable when paired with heavier switches and tried out with a short adapting period.
The upside of SA is that SA is perhaps the most aesthetically pleasing when we look at the caps as sculptures, and the doubleshot artwork on SA caps, due to its semi-gloss finish is also the most clearly visible. And in terms of wall thickness and pressing feel, SA is definitely rock solid.
3. I personally think DSA is cute, but is more suitable for ortholinear and smaller keyboards, like the Planck, or the Subatomic. Uni-profile like the DSA does not facilitate reach when the keyboard size gets larger.
