[Antennas] 2 trees 150' apart 60' high

[Lefczik, Larry D]

I have 2 pin trees about 150' apart and about 60' tall, about 200 feet
of #10 insulated stranded wire and 100' of 450 Ohm ladder line.  My
tuner has a balanced line input and I also have a 1:1 balun handy.  I
also have 50 and 75 Ohm coax cable.

I am looking for all band operation, but with the way bands are now I
probably should concentrate on 75-20 Meters.

My thought is 150' dipole fed by ladder line to the tuner is the best
use of the space.  
Would a 125' 75 Meter dipole with the balun at the feed point and coax
feed be a better choice?
I had a G5RV up for many years but one leg broke about a foot from an
end insulator, should I just fix/shorten that antenna and put it back
up?

Any ideas?
