	Significant, yes. I'd just like to be able to tease apart the various  
factors involved. I'm curious about the particulars of experience to  
date (understanding that, unfortunately for the notion of experiment  
versus control, the experiment is also a different scale and design):  
is there still the familiar pattern of lowest plain wires on the  
treble bridge, and lowest strings above struts moving farther? Just  
not as much? (guesstimate about the proportion? half?)  Do unisons  
continue to smear in the same direction? Just not as much?
