Hi Neil,
Nice score from up there. I would like to hear about your new 40 meter antenna 
??  I have been wanting to put up some type of directional antenna on that 
band. I had a half square pointed NW/SE
a couple years ago and it worked pretty good. It fell down and I never did put 
it back up.
Right now I have a 40 meter zepp @ 50 ft and wire vertical with 4 elevated 
radials. Both work OK.
The zepp favors EU but I notice it has a null to South America. The vertical 
covers that direction
nicely. I have been thinking about some phased verticals for 40 meters.  I have 
also been thinking about putting up anothor inverted L on 80 and phasing those 
as well.
I have and idea for your problem on 20 meters.  My zepp acts like two half 
waves in phase and pointed in a NE/SW direction in favors those directions. I 
have just put up a simple 20 meter 
dipole - broadside NW/SE. It works great. I have no problems busting CARR and 
AF pileups.
If you want some directivity maybe try a 2 el switchable quad. in the 
directions you want to cover.
I also remember W4AN had a 4 square on 20 meters.  Verticals seem to work 
pretty good on 20 meters.  My friend K8MR has done some tests and in some cases 
a vertical will outperform a 
horizontally polorized antenna on 20 meters...
73, Jeff
