Any possibility of putting it in the ground a bit, (or pour a little concrete or bury three of those pre-cast concrete pillars they sell at HD or Lowes for the base), attach a house bracket to the upper part for stability, and then you could probably use 25-30 feet of it without too much trouble. Probably more if you just nest part of it when you aren't using it. Or as mentioned above, you could do some inverted vees which would act as guys. I don't know what you currently have, or if this would even be an improvement. Just thinking out loud..............
