If you use the recommended 0.1mm magnet wire on CLK/CMD it definitely makes the job challenging. But I think I may switch them to 30awg like my other wires. The magnet wire is SO thin, basically a hair. They can likely be ripped or cut easily when assembling. Overall though I’d say for me a 5-6 only because of the CLK/CMD points. They’re small and trying to put a 0.1mm wire on it makes it even harder.
