Yes, I discovered that the AES dial cord does stretch quite a bit.  When
restringing the dial cords on Duanes SX-110, I restrung it several times
before figuring out exactly what was happening.  Like you said, worked good
at first, then next morning, "no turnee".  I solved the problem by tieing a
power Xformer weighing a couple pounds on one end of the cord and suspending
it for a couple days.  Worked very well.

ALSO, I found that the "medium" dial cord was much too stiff, like it had
hardened.  This made it impossible to string a cord that wouldn't slip on
the 1/4 inch shaft.  The smaller size works fine after you pre-stretch it).
I had bought both sizes to see which worked best.

Incidently, when I restrung the 5R10A, I DID NOT pre-stretch the dial cord
(3 of them).  So far it is holding up just fine after being stung for a
couple months.  But I believe that it's cords are much shorter than the ones
in the SX-110 were.  Also, I found that where there is room, it is far
better to put an 'extra' turn on the 1/4 inch shaft.
