For crying out loud ...

Say a prayer for Lou Varney and all the other illustrious SKs.  Then ...

Get " what ever version G5RV " out of your head.   Imo, it's been 
bastardized into a buzzword to trap the unwary into buying frenzies.

Think " random dipole ", " random open wire feedline ( " owl " ) ", and " 
good balanced tuner ".   You can adjust feedline length to get the skyhook 
you put up to tune with the tuner you have.

You can run an owl feedline without a balanced tuner or a balun, but the 
results are unpredictable.  Pretend it's the best you can do with what you 
have at the time and ignore the flames sure to follow from that remark.

Put up a wire as long as you can or want, cut it in the middle, attach the 
feedline and rig, adjust as necessary, and CU on 40M c-w.

73, Dave, N3HE

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'.
