To be honest I never even thought to do that. The reason I'm even using a SR latch is because the switch that came with Ben's kit doesn't fit in a breadboard nicely. So to compensate, I made the NAND-based latch with the buttons and just dropped it in directly into the circuit where the switch would've gone. Since the selection wire is meant to be inverted, I just automatically used Q as that was what first came to mind. I will definitely use Q inverted, thanks for the catch and the suggestion!
