if you think about it and visualize it... what is best is getting the anchors 
  (fill those pipes with concrete!!) out as far as possible to assure as low 
angle as possible.   As stated, Not Less than 80 feet.  Further if possible.
the distance beyond that should not make any difference as long as they are 
within the spread that you have mentioned.  I think that you are just fine.
I plan to put mine in with about the same distance spread that you have.
My concern is phillystran vs steel cable.  since I am running dipoles and 
long wires, I want to avoid detuning from metal cable and I am hoping that 
Phillstran is within comparable strength vs some huge percent of a lesser 
amount of detuning.  Phillystran sure is expensive but...

anyway, good luck, you should be fine.
