      Using Roslau wire of the same diameters? or using the Roslau wire of the
same gauge number? 1000 to 1500 lbs  seems like a lot for the change. (now, if
you do go by gauge number, you will be .001" lighter  on all notes +- some
conversion differences.  This I could see taking a lot of tension out).    
    And wouldn't it be necessary to mention size when describing the "North
American Piano", Since there is considerable difference in tension between a
Baldwin SD-10 and Steinway S.
