Force110 and high winds

Just wondering how people have found the Force110's in high winds?

We've recently had some severe storm force winds battering us - gusts up to 160km/h.

This has resulted in a number of our Force110 installations shifting and having to be realigned.

I notice the data sheet gives a figure of 140km/h for wind survivability.

I think Ubiquiti's Power Beams are in the region of 200km/h.

Is anybody else deploying these in high-wind areas?

If so, are you using any extra reinforcements - extra clamps etc?
