Against large scale 10' high nettles ...

When ever have you seen nettles 10'high? The ones growing around the fruit
bushes will get to 6' to find light but out in the open 3 or 4' is the
maximum.

Nettles don't like being cutdown, even the swathes of nothing but nettles and
a good root matt are much reduced(*) by strimming a couple of times a year.

ie. A few nettles amongst the grass, rather than 100% nettle.
