No.

65 feet is a quarter wave. This will require a GOOD ground, plus most
likely the highest current portion of the wire (that nearest the ground)
will be vertical, thus adding ground losses to cross-polarization losses
to losses due to low angle radiation when high angle is needed.

The 130 feet is an end-fed half wave, requiring a tuner to feed. The
high current point will be in the MIDDLE of the wire, likely horizontal,
and reducing ground losses at the feedpoint to near single digit
percentages.
