I >have not experimented with altering wire size in this range, but I am The problem may not be the wire size, but the mass of the hammer and/or the shank. Practically every new (and sometimes older) piano I see has treble hammers which are far too heavy. If it's an older piano the hammers may just be worn out. Sometimes it's just a poor piano. I just put a set of Renner Blues on a 48" Willis upright and they went on beautifully. The original treble hammers had been thinned down in the factory to slightly larger than the shank itself in the last few notes, and I had to duplicate that to remove the knock. Taking some wood off the sides and occasionally under the treble hammers of some of the newer pianos where they haven't done it already seems to help the tone a lot at the top end.
