LV Mastery Question ... Main Shifter and Command Global

[Ziaholic]

I've been adapting our team code to be more like the code in the LV Mastery videos. I've watched many of them, many times, and am trying to follow the advice of not actually "doing" anything within the Teleop.VI

I've added a shift register to the primary While-Loop, calling it Main Shifter.

I'm toying with different architecture decisions now, but the TipJar videos don't necessarily address my questions.

Primarily, I'm torn between a couple choices that are interrelated ... namely the Main Shifter, and the Robot Command Global.

If I make the Main Shifter a Global, and write to it just before the main loop cycles, then I don't necessarily need a Robot Command, as long as those commands are in the Main Shifter. Right?

I know that I can get it to work either way, but I'm just wondering which one might be more efficient and/or more wasteful.
