The only reason I could think of to use larger---fatter---radiators is to increase bandwidth. If you build a loop for 80m you'll probably be able to work the band with only retuning once or twice. The higher bands should be covered from egde to edge at 2.1-1 or less. Suggestion---160m loop, then tune to the band centers and work away!  **disclaimer**  What worked may or may not work there!

 the arrl antenna hanbook says that with a half wave closed loop the easiest way to match to it is to run another loop a few inches below it and conect one side of the coax to the top loop and the other to the lower loop. It might work with twin lead.
