The pullouts probably ripped out because whatever reinforcement patches there were, were too small to spread the force over a large enough area. Ideally, the manufacturer would have strategically run a seam in the netting through that location.
So it is a matter of sewing on larger reinforcement patches, with stiches at both the outer edges and further toward the center of the patch. Circular patches look nice, but for me, I would just sew on a hemmed rectangular patch with the conventional box and cross-bar X stitch, because I am lazy.
Know nothing about bonding netting. The ordinary urethane glues, like Elmer's are pretty good for many materials, even though not Hysol. Because ordinary urethane glues foam and bubble when drying, am planning to test some GE silicone glue on cuben, but haven't got to it yet. Wouldn't do anything without testing first for strength of the bond with some scrap materials. A stiff and inflexible bond will limit the ability of the patch to distribute force, which is not what you want.
Don't think you need 210 D patches. Anything way stronger than the netting is overkill.
Won't try to add to the already excellent contributions on this site about bonding and sewing cuban reinforcement patches.
