one other thought on Rod:
If your goal is to use the rod for setups, then I think the move that works best with it would be the Rolling Thunder. Lock the opponent down down in the bubble, then throw out the cloud and hopefully force them to eat DOT or get hit with a setup. Something like Lightning Storm, Rolling Thunder, and Lightning Rod could have some potential synergy there. Lightning Storm can be used in conjunction with F4 for some braindead poke/chip pressure, and options on opponents wakeup. Or you can trade out lightning storm and use storm cell, that way you still have great combo damage.
I think if Super Bolt makes sense in a variation, it pairs better with something like Quick Charge and Electric Current. It gives Raiden a way to get in and pressure wakeups after ending a combo in Summon Lightning.
