I'm currently building a stunt crossguard out of PVC and am trying to figure out wiring. I'm completely new to wiring sabers so please bear with me.

1) Would it be better to use a tri cree for the main blade and a single cree for the side blades, or have all the blades on single crees?

2) Would I need to use a 7.4 battery for the three LEDs?

3) Would I need a resistor for every LED?
