Is it still a G5RV if I run more ladderline to it?  

I can't run all ladderline because I don't have a balanced tuner, so have to go through a balun.

What I was running previously was a 170'  dipole with ladderline feed from outside my shack.  I ran approx 8' of coax out to a 4:1 balun, and ladderline from there.

During Hurricane Ivan, one of my dipole supports (big, tall tree) blew down.  Now, I have a reduced horizontal span of approx 105'.  But, will still have to run coax out the shack window to the balun.

Should I add some downdrops on each end to help loading?  15' of downward ends would give me an effective 132'.
