[TowerTalk] 160 Meter Antenna on a City Lot

Ladies and Gents....
 
This summer, I lost the far leg support of my 160 meter Inverted-L.  The 75 foot elm tree did not survive a 90 mph micro-gust (the tower did) and it broke in half.  I have to cut the rest of it down.
 
That leaves me with a problem.  I have other place to hang the horizontal leg of the 160 meter Inverted-L.  So, what do I do?  I have a 60 foot tower with a TH6DXX on the top, but my track record of shunt feeding the tower is not all that great.  Yes, I have a pretty good ground under it...not great...but OK.  I've used a lot of different variable caps on the shunt but tuning it has been 2:1 at best.
 
How about a trapped dipole?  I can get a 80 meter inverted-vee on the lot.  So, I was wondering if a trapped system would work and how well?  I would think that the band width of such a device would be small, but so it s a shunt fed tower. as well as the Inverted-L.
 
So, anyone have some great ideas?
