I did try the feedback loop inside of a while loop. It appears to work exactly the same as my previous loop (which is good). How is this more efficient?
No, a feedback node is not more efficient, it migh just lead to a bit more compact code that is easier to read, especially if you have a lot of other code inside the while loop, because it eliminates the long wires connecting the shift registers and keeps related code more localized instead of spread over the diagram.
Note that a globally initialized shift register behaves slighly differently from a shift register if you would call this VI multiple times as a subVI, for example. So check the online help to decide what behavior you actually want. For a toplevel VI, they act the same.
