Hi, Alan,
Universal strings are a big compromise at best and at worse can severly
compromise the tone of a good piano.
That being said the first step is to match the core, this determines
the inharmonicity. The wrap is matched next and here you have options. A
smaller wrap reduces tension, a larger one increases tension. I would go for a
slightly smaller wrap before a larger one.
Most pianos are poorly designed in the bass department but that is
another post.
Hope this is helpful.
