Why would the wind tend to twist the ladder? Is your antenna highly
asymmetrical? I would be more concerned by the bending forces which can
be very high if the antenna is a considerable distance from the highest
guying point.

Even if the antenna were not symetrical, that bending would cause enough
assymetry to be bad. The only thin tall antenna mast I ever put up long term
was a receiving dipole for VHF, based on a thin angle-section scrap peice
from a a very long discarded shop front sign. It was as thin as a reed, and I
figured out that if I guyed it such that the flex above was countered by the
bowing below, then few gusts would ever cause it much risk. It twisted a lot,
but very gracefully, and despoite storm force widns it stood for fifteen
years until it rotted where it stood. The wind never harmed it, but
corrosion eventually did.
