I hope that will include the suggestion of placing the balun between the rig
and tuner, just so you can report back on it.  K7EL of EZNEC fame wrote
pretty extensively on this several years ago.  I've tried it, and it seems
to work, but I was never quite comfortable not grounding the tuner (not sure
why).  But if you look at Palstar's balanced tuner, that's exactly what he
does.  There are similar balance-L circuits out there, so it's probably
worth a try if you don't want to spend a lot of time trying to find a
combination of feedline and antenna length that will make your balun happy
on several bands.

Let us know!
