[pianotech] Yamaha C7 scale

Right you are.  Typing a bit too fast.  The low tensions generally
associated with that area create that weird sound and poor transition to the
much higher tension bass section.  It sounds like someone upped the
diameters from the original as indicated on the bridge.  I'm not sure that
is a benefit.  At best it's trading one problem for another.

Larger wire raises inharmonicity and tension, but the break% 
stays the same.

Since you're keeping the bass strings, I'd say just go with 
what's on the bridge.
