Don,

Others are far more knowledgable than I, but top loading has less loss than 
base loading so the L should perform better, all else being equal.

That said, I have been using a 60' base loaded vertical with 8 elevated radials 
and have 136 countries from a 1/4 acre city lot in the black hole of 
California,  I suspect the total would be a lot better with an L!

Good luck,

Bob
