Default Metal mast for inverted V antenna support--will it work?

Amazing we have not heard from the "EZNEC Experts" with plots of a metal
vs. non-metal support ...

If the wires of the dipole are exactly perpendicular to the feedline,
and
no common mode currents, the plots should be the same.
The more sloping, the more coupling I would think, but even then,
it's rarely a problem.
