[ODPILOT]

Good suggestions.  No I didn't try tuning it back and forth to even out the tension but I will try it.   I think also that in the process of stringing it and keeping tension on it as I do it,  the string does stretch.   I think also perhaps, it's a mistake to set the length of the cord by looping both ends permently  before I string it.  I think maybe I should leave the end unlooped and then wrap on the spring hook and THEN make a knot.   Thanks, will try again.
