When I suggest roughly polished strings instead of smooth heavily polished ones, I often receive a squint like I am interfering with personal choices on musical taste, or with technical issues of an instrument which I have never seen, let alone played.
It's always been difficult for me to explain why I am firm on this point. It has been difficult because it involves some production secrets which probably have not been shared before. They are not big secrets, but they need a bit of a technical explanation to become perfectly clear...
In this report, I finally explain why I never recommend smooth strings, and why I think there is always a better solution than that, even when you think you are an exception.
Ps: the responsibility of all the drawings is entirely on my shoulders, including the Merry Bunny dancing in the equisetum field.
