Okay got home my first neca display stand and damn, it does it purpose so far perfect and from now on I will get one for each alien as it solves all issues with the neca aliens, ok almost:
One can now get the alien into a walking pose or jumping etc and the tail can be posed however one want, no more being forced to use the tail for balance and the legs close together to keep the figure up and poses are limited.
Also the stand takes the weight off from the alien so the legs are barely touching the ground so it will indeed protect the legs and the joints.
Pictures of my defiance alien that I have posted pictures of earlier, can see the repairs on one of the legs and one of the arms are very loose but hopefully its not easy to see:
This one is just to show how bended the legs are from having the figure to stand on its own legs for 3 months....
