The difference between the two is vastly overshadowed by the difference 
between excellent, decent, barely, and poor radial fields. Spend all your 
plotting and scheming time on how to get down 1/4 wavelength radials, if at 
all possible, with no more than 13' separation at the ends of the radials 
you can put in.

If you are supporting the bend with a tower, the L is just an odd way to 
load the tower, and an additional set of issues is in play, including the 
radials.
