That depends on what distances you are trying to work.  200-600 miles, the horizontal part may provide the most useful radiation.

My ARRL Antenna Book suggests 160-170' feet may be the easiest to load on 160.

There is nothing wrong with a multiple of a half wavelength.  That's the length for Zepp antennas and "Two half waves in phase" antennas.
