I will say up-front that patents and patents pending on this design should be respected. I've been here at HF long enough to see that nobody else has presented either the analysis of loads and forces or suggested the engineering solutions. So: Kudos and profits to the company that brought this to market.
That said, Wise Old Owl's presentation cannot be uncommon. Everybody who has tried to drive stakes -- more often in the population of campers for a tarp or tent because hammockers are more rare -- has faced this problem.
The difference with tent or tarp / rain-fly is that the exact location of the stake is not critical. Small rock in the way? No problem. Try again somewhere within a foot / 30cm radius. Surprised to hit a root? No sweat. There may be optimal locations, but second best, even 3 feet / 1 meter elsewhere is likely OK, at worst with a few adjustments to other lines.
So, Jason: When presented with a lot of difficult soil, which plates and spots on the grid are most critical in getting the stakes well-anchored? Or, does your analysis and engineering design result in well-shared loads?
