Here's something I came up with to add motion to my DSD. I've used stakes on either side of a Pretty Boy before and could get about 120° of motion with that setup, but this let's me get a full 360°. It can be deployed quite quickly, and it should work with other decoys as well with some modification.

In case anyone was considering the Zink Lifeline 360 to achieve the same thing let me save you the hassle, it's not rugged enough to support a DSD Strutter and I'm not even sure it would fare well with a Pretty Boy on it either.
Interesting... I'm going to look into this. Thanks for sharing
