In the real world we try to get maximum results with minimum investmennt
in effort and materials. An unbalanced 1/4-wave or a balanced 1/2-wave
seems appropriate.

As far as angles go, polarization is the direction of the electric
field, usually horizontal or vertical for mechanical as well as
electrical purposes.

You can take Kraus to the bank. Check his index for "Mutual Impedance"
of paralleled dipoles or echelon antennas. Better yet, you likely have
experience with trials of cross-polarization of VHF or UHF antennas. You
have seen the havoc cross-polarization causes. Now, is there any angle
between fully aligned and completely misaligned where we discover a
magic peak? Of course not.
