I’m familiar with the wound 3rd string from a particular Savarez line, although I don’t recall it being wound in the traditional sense, i.e with a core and outer winding. It was more like a ribbed plastic.
It’s definitely a personal preference issue. For me it doesn’t work at all, and is a hindrance to achieving the kind of tone I’m looking for and for playing the kind of music I like, even though it isn’t all classical.
On a steel string, the third wound string seems perfectly normal to me and I wouldn’t have it any other way. But on nylon? Totally different beast.
But, your preferences may be the opposite, and your opinion would be just as valid.
If you’re curious about it, just give it a try for experimentation purposes. Nothing to lose.
