For a 100' tower with EHS guys broken into non-resonant lengths, you
will be putting 30+/- grips on, so buy some good gloves (maybe 2 pair)
and be prepared for some sore hands. However, they are the only way to go.
If the responses didn't explain how they work, just go look at most any
telephone pole guy ends.
They are usually rated to have grip/break strength equal to the wire
they are made for.
