I found this pic of how I had my TK for a while. I didn't realize this thread existed until today, so I will post it here.
This is unicorn vomit from a crap bag sale. Because SA profile > coherent legends or homing keys. This is ugly as sin, but I did like having my own pseudo-homing keys. The top row 1 and the W key are the only keys on the TKL portion which use a profile besides Row 3 SA. This was nice for video games. There are some other Row 1 profiles on the TK, but they are just there because it looked better than using letter legend keys.
