Try a tree spike
I started this a few years ago by accident but now its the only way I hang my hang on stands. I place a screw in tree spike into the tree and "hang" the hangon stand on this spike. Then rachet it the to the tree. Stand doesn't move at all once its strapped down and is very steady. May be a little over kill since they are designed to dig into the tree once you put weight on them, but its about all i do now.
NE doesn't allow you to use screw in spikes on public ground so I can't do it there but all my private ground stands are setup this way.
