What a well thought-out posting!
I don't like BX-series towers at all. They are "rated" by Rohn for antennas
having 10' maximum boom length, and I tend to follow that advice -- these
non-welded towers have little torsion strength. After 42 years (if it was
really installed in 1960), it has less.
If it were me, since I like playing with towers and antennas anyway, I'd
take down the whole mess and sell it off to help raise money for a good
crank-up tower. A W-51, HG52SS, TX-455 or other used 50-55' telescoping
tower would be a far better deal in your situation: No guy wires, and a
tower you could retract when not in use*, to minimize XYL and neighbor
impact. And one easily capable of supporting rotary beams up to about the
TH7DXX size, should the opportunity arise in the future to install such a
*Note: Telescoping towers have one more advantage: They can be height
optimized for the band and conditions. Sometimes 60' is way too tall to
work close-in DX on 10 meters, and 30' works better. With a retracting
tower, you can accomplish that in a minute. With a fixed tower, you cannot.
