I just have to agree with Gray Beard.

A bit more weight means the ability to tackle the wind and gusts much better and makes it easier to fly in such conditions which are not rare.

I was planning a posting along this line and thanks to Gray Beard to have read my mind .

Light weight or lighter weight promoters can stay on the ground with no more than 12 oz/sq ft and watch pilots enjoying defying wind gusts with their models in the 20 (2x) oz / sq ft.
