I have watched and read quite a bit about putting together multiple payloads stringed together, given that you can do that is there really a reason to have more than one ducky? Maybe a Red pill, Blue pill ducky depending on what you are trying to do? But my thought would be you would have some foreknowledge of what you are going to need and what payloads you would have on your ducky before you tried to use them.... what am i missing?
