One very good source of information on OCFD antennas can be found at

He also has a very good discussion and examination of various baluns,
common mode chokes, and tuner loss.

So not much different than the G5RV with parallel feed line all the way to
the tuner, no coax.
Just fed off center at the 39% or 61% point instead of center fed.
I wonder about losses in the tuner due to the imbalance but not having
tested it I hold any judgement.
Several articles in the literature of similar OCF antennas fed with
parallel line.
Basically all are non-resonant, so no worries about resonance on higher
bands as with OCF , balun,coax fed antennas.
I used a 88 foot center fed with 2 lengths of RG 6 coax similar to what you
are using.
From Ecuador I worked the world with QRP 40 to 10 meters and with 50 to 100
watts on 80.
Yes, a good antenna. I center fed it due to worries about loss in baluns
with OCF antennas and the lack of commercial balanced line. Just a little
loss from the RG6.
