I have used the W3LPL 8-circle in a TBDC (a TBDC that was 99% domestic stuff). The 8-circle is surprisingly directive. Almost all strong signals just drop down into the noise if you are two notches off from the best direction.
Now the 8-circle gets a big number for RDF rating, but I don't think the RDF number fully captures how directive it is and how deep and wide the null is, in any other but the chosen direction. I was using Frank's beverages as on the second radio much of the time. In comparison the beverages seemed pretty much omnidirectional. Don't take that as anything bad about beverages, just take that as a sharp contrast to the deep null you get for 270 degrees with a well-installed 8-circle.
