The only bands I have found where verticals are preferred are on
80 and 160 meters, which is good because of the impractical size
of Yagis on those bands.

Not necessarily so for 80. For years I used a delta loop array (flat
topped) facing NW, NE, SW and SE, average height of 130 feet which was
suspended on
a caternary system from three different towers. The system blew away four
squares.
Generally speaking however, unless the Yagis are close to at least 1/2
wavelength in height, the four squares are the way to go...especially when you
consider the maintenance. Those low angles just don't come that easily unless
you get the Yagis up high and in the clear.
