I suspect that the twist is bidirectional over the length of a year. Thus the length of the PTP that is being used matters. The amount of play that you have on that link. The longer the link the less play. So you would need to ask the length of the PTP link

So it sounds like maybe different style pole or kind of tree it's made of could make the difference if some are see the twisting and bending and others don't. Or maybe the way it is cured and treated by the company that is supplying them is the difference.

On a 13 mile link the RSSI dropped from 63 to 72 in about 6 months. That may be a minuscule amount of twist, but enough to drop out of QAM 256 to QAM 16. QAM 64 is still enough to handle the load on this particular link, but QAM 16 is not.

We use them and twist isn't a problem but since we don't have a bucket truck arranging access to the equipment is a problem.
