I thought stranded came out the winner in the great wire discussion here a few 
weeks ago.  I remember the THHN from Lowe’s part, but I forget if it was 
stranded or solid…. BTW if the weather is bad enough for flying debris, I don’t 
think I would be operating.  I would have myself in an inside room without 
windows  :-)
