Or should I just dismantle it and go back to positioning the GSRV Mini.
That, at least, is a copper dipole.

I won't presume to tell you what you "should" do. There are
too many unknowns in your system. You may need to spring for
an antenna analyzer, like the MFJ-259B. If it were me, I
would junk the slinky antenna. At least the half-sized
G5RV is known to work relatively well on 40m, 20m, 10m,
and 6m.
