    Thats what I meant by 'nominal'.   I was told the 1/8" 1x19 has a
    larger diameter than a 1/8" compacted wire.  Let me google it. ... 
    <br>
    <br>
    oops, looks like I'm wrong based on:
    <a class="moz-txt-link-freetext" href="http://www.rigshop.com/site_pages/products/standing_rigging/wire.html">http://www.rigshop.com/site_pages/products/standing_rigging/wire.html</a><br>
    Just a couple datapoints, ... don't use this for your decision. <br>
    says 4mm compacted is ~same strength, 16% smaller diameter and 10%
    stretchier than 3/16 1x19 .<br>
    says 4mm compacted is ~same diameter, 30% stronger and 24% lower
    stretch than 5/32 1x19<br>
    <br>
    why the stretch and strength differences are not the same doesn't
    make sense to me...<br>

                          In a nasty blast a few weeks ago on the Bay,
                          Carlos' mast suddenly went sideways, outers
                          parted at the top and inner at the bottom. 
                          Amazingly mast is fine (and so are all the
                          crew).  So I need to replace Carlos' standing
                          rigging, and someone suggested Dyform or
                          "compacted strand" wire.  They are both SS
                          wire but pack a bit more steel into the same
                          diameter (I think) and are therefore somewhat
                          stronger and less stretchy.<br clear="none">
