One question, if shorting the leads to feed the g5rv "marconi style",
would it be better to connect the single wire to the antenna tuner's
random wire connection, or to the coax connection, or does it matter?

It's hard to say, because too many variables are involved. What I'd do
is to model the antenna with EZNEC and if the impedance is high use the
random wire connection and if low the coax connection.
