I don't know that it will, one way or the other.

Refine string spacing after how many years of being where it 
is? Has this really been a problem in older pianos with half 
round or oval counter bearing bars? I can't say it has been 
for me, but then different locations have different realities.

What profile? My counter bearings don't define a speaking 
segment, so they don't get profiled. They get left at the 
radius of the rod they were cut from.

Yes we do, and at what tonal penalty?

But we *can* ask more specific questions and examine the 
premises around which our questions are formed for validity. 
Ever read Ayn Rand? Whenever you are facing a contradiction, 
check your premises. One of them is wrong.
