I could be mistaken concerning the ARRL Technician video course, but while I
was attending the technician classes with my 13 year old son last year, I
saw one of their crew (during their short tower safety demo) climb an
extended crank-up tower. Isn't climbing an extended crank-up not
recommended by tower manufacturers because it's a dangerous practice?
At least the crew was wearing their hardhats...

I guess I'll be a nag...
I have a class of 7 kids taking the ARRL Technician video course.
In the Safety Practices section of the course, the instructor
(rightly) makes it very clear that in no way should antennas
be put up where they could contact power lines, should either the
antennas or the power lines fall.
It also would seem that a 100' self-supporter would have very limited
capacity (unless it is a big expensive cell tower or something), and that
any normal ham-class self-supporter of that height would be
severely overloaded with that much antenna at the top.
No offense, and there are certainly details that were not provided,
but it seems to me that these plans need revising.
