[TowerTalk] Wire Antenna Dilemma...Help me decide!

I live at a secondary QTH during the week and was given permission to put up wire antennas.  I was thrilled because there's some really tall trees here (>100').  I picked the nearest, tallest tree, hired a local tree climber and installed a Cobra Ultralite Senior (linear loaded multiband antenna, 140' long, fed with ladder line).  Works like a champ and even loads on 160m, all through the rig's internal antenna tuner.
   
  I mounted the dipole as a sloper because mounting it as an Inv Vee would have put the feedline too far away.  The one end is at 100' and the other, at 15'.  The feedline is at about 50'.  I'm getting great signal reports!
   
  The next tree of similar height is about 250' away.  I figured the sloper would be closer to my shack, with minimal visual impact, so I decided to use the one tree only. Now, I want to use that second tree 250' away!  Question is, should I string rope to that tree, suspending that other dipole leg to the 75-100' level vs. the 15' that it's currently at?  Or should I maintain the status quo with the dipole and maybe throw up a longwire, as a second antenna?
   
  The LW would be about 300' total, including the vertical element, though I don't want to cause interference.  Your input is greatly appreciated.
