I just noticed that Acrolink has 16 core versions of their 8 core cables as well. They seem to be the same in terms of material used with just geometries being different:
A) 8 core, 19 * 0.10mm per core (

B) 16 core, 7 * 0.10mm per core (

A has a larger equivalent cross-section so should have better conductivity, but I imagine B should be softer because of the more distributed thickness (and also being thinner overall). Then again, you have more "sleeve" material, so maybe the opposite is true. Any thoughts? I'm hoping B might be the best compromise for me between build, performance and ergonomics.
