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

the most efficient way to go?
Efficient - yes. Fast - yes.
> About the only concern is that the foldover back-boom is not in the
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.
