If the top loading wires have to slope down due to a lack of tall 
supports, it makes sense to use as many wires as possible, so that 
each one can be shorter (for the same resonant frequency) and thus 
cancel a smaller portion of the current in the vertical 
radiator.  This assumes that the low support points remain at the 
same distance from the vertical radiator and that the ends of the top 
loading wires are supported by insulating extensions.

You can also create a spider-web by adding wires horizontally between 
the ends and/or middles of the top loading wires.  This increases the 
capacitance and allows you to further reduce the extent of the 
capacity hat and the resulting height of the sloping portion.
