For the private implementation, you can use either the feedback node or you can add a loop that executes for only one iteration and place the shift register on the loop. You do not want a continuous loop or your teleop will not return in time for another teleop packet to be processed.

There is very little difference between the runtime behavior of the shift register and feedback node. The shift register can be grown to hold multiple iterations of data, but the feedback node is slightly easier to initialize. The choice of which to use is largely a matter of choice.
