Conclusion for me about the product TriAx Geogrid:
13.1 ft by 246 feet: 115 lb
3223 sq ft for 0.356 lb/sq ft.
So 200 sq. ft >>>> 7 lb for HG sail, assume zero for fill of the apertures (holes, openings) and the involved glue. That is heavier than I want for my HG sail.
The product has sharp edges; gloves are to be worn when handling the product; such all leads to a "No" for me on its use. Too heavy; logistics: too involved. Apertures are smaller than what might meet my aims.

But a triaxial Dyneema constructed net might do wonders; it appears the net would have to be DIY project. Names for the openings in the net: holes, openings, apertures, deductions, .. Holes can be any size when one makes one's own net.

Joe, A calculation error here I think:- 13.1ft x 246ft = 3222.6 sq ft 115 divided by 3222.6 = 0.0356854 lb/sq ft. Must have been a typo as you end up close to the correct figure of 7.13708 lbs for 200 sq. ft. However if you are only using it around the leading edge/pocket area then weight would be much less. As you say a triaxial Dyneema or a springy nylon type material net could be the way to go as an insert in the pocket.
