plenty of  work

Yep. It's kind of a pain but not really that  difficult - especially the 25G

    It should be guyed in 4 directions just below the  hinge per Rohn 
instructions so I'm not sure why you'd have to re-guy it  unless it was installed

    Efficient - yes. Fast - yes.

plane of the direction we would
drop the tower.   It would  strike first, and could damage the boom,  
or the hinge.
    You're talking about chopping it down. OF COURSE  just about everything 
will get damaged to some extent. 

>  As a variant, we MIGHT be able to get at the top section,  and remove  
it...which would allow the
section above the fold to  go to vertical, and thus move the back-boom  
away from  harm.

    Sure. Just be sure to put a tagline on the top  section to keep it under 
control on its way up. 
    All of your scenarios will work. Just be  careful.
