I believe the reason that verticals work better on lower bands is a result
of lower takeoff angles on the low bands, low frequencies, whereas as you
move to higher frequencies, the takeoff angle seem to be higher also, 


I don´t think so. Radiation angles are determined by the height of the
reflecting layer of the ionosphere and skip distances and probably almost
the same on high and low bands, if not higher on the latter while more hops
are necessary.
But, dipoles at low height and especially invertered V dipoles have much
less gain at 10-12° then a vertical.
A dipol at one wavelength will always beat the vertical with its additional
ground gain except the vertical it is above salt water or the dipol is
facing the wrong direction.
