One thought I had, was to go with the C4, and just have it all on one boom, but that would be the ONLY thing I could put on that tower then.  I'm trying to find a happy medium between performance and wind load.. Plus, I'm trying to get some VHF/UHF stuff up there as well.  I may get stupid, and just add a 3rd set of guys, because one of my solutions was right at 10.3 (It's rated for 10.1) sq. feet and I get everything I want.  (Yes, I know.)  I also know that in my area, I seldom get gusts above 50mph.

How about a C3SS?

Perhaps you could add drooping extensions to either
end of the boom and load it on 40M?

You may still have spare tower capacity for a vhf/uhf beam!
