Your intuition is right on. :) There's another fine option to consider,
it's in your price range, it offers the best of both worlds, AND it
works just as well on the WARC bands and 6M. I'm talking about a
SteppIR. I have the small 3-el (no trombones) with the added 6M element
that covers 20M-6M. It's an optimized monobander on every band,
4-elements on 6M. It's also light enough that a strong guy on the tower
can handle it by himself. And it's modular, so it can be built and
tested on the ground, then you take off the elements, pull it up, and
put it back together. That way you don't have to weave the elements
through the guy wires as you bring it up.
You can, of course, go for one of the larger SteppIRs if your tower,
your neighbors, and your budget allow it. I am VERY happy with mine. The
DB-series antennas get you 40 and 30 with gain, but they're a LOT bigger
and heavier, there's more to go wrong, and they are a lot more work to
install. SteppIR is not great for customer service, you'll wait a while
to get it, but they're very good antennas.
Another major advantage of the SteppIR Yagis is that you can reverse
them in about 5 seconds, or set them bi-directional in that same time.
That's VERY handy when the band is open to JA and South America at the
same time (which often happens in Calfornia), or to EU and VK at the
