Topband: Inverted l or 4 square?

[Jim in Waco WB5OXQ]

If I can support a wire antenna at 50' or maybe more in tall pine trees and have 1.9 acres of space to use which would work best.
Lots of tall pine trees on the lot.  I assume the trees in the center of the square will really not be an interfearing factor.  If I feed with 
window line will it work well for a multiband antenna?  I assume the inverted l will need long radials to work well and that is possable, does the square antenna also need radials and if so how oriented?  Prospected area of installatiion south Florida.
