Pitch raise reply

[pianoman]

Hi Rob,	You know that sounds like a good idea if you could find a place to
keep the broken strings from getting messed up as you carry them.  I wonder
if they would be more stable  when using them as a replacement as a tied
string, again because the stretch in the wire has already taken place long
ago/  Any thoughts?
