The wildedge step is very stable IF THE KNOT IS TIED PROPERLY AND SLACK IS REMOVED LIKE IT SHOULD BE. Now with that said there is a learning curve for them and it shouldn't be learned the day before the season opener and not at twenty feet either.
I have tried many different things with mine, 5 step Yates big wall ladder FAIL , 4 step aider FAIL , the wildedge aider this works alright cuts number of steps needed to get to the height you want to with only half of the steps. Knaider / swaider was interesting I ended up Just like
@rutjr hanging sideways in the tree.
I have also removed the ropes on mine and have installed flat 1 inch webbing instead and tie the webbing using the same knot as the rope. This doesn't stretch like the ropes so it removes some fiddle factor while installing steps.
