All good points from you, Brian, and others. I've done some simple Yagi 
designs using YW, optimizing for forward gain over the needed bandwidth, 
because that's what I need on the lower bands, and they're relatively 
small, because that's all I can turn between the trees in my dense 
redwood forest.

As to the particular 6M antennas being discussed: when I moved here 20 
years ago, my QTH was pretty quiet. Now it's not, and I have strong 
sources in three important directions -- Asia, Europe, and South 
America. So my limiting factor is more often HEARING, rather than being 
heard. Further, on 6M, my primary interest is weak signal work, which is 
all concentrated within a little over 200 kHz.
