EFFx, I think he's saying something totally different.
impulsegrenade_self_impulse controls if you can impulse yourself, right?
FFA controls if you can impulse teammates, right?

Now think about this: FFA is 0 and impulsegrenade_self_impulse is 1. You should not impulse your teammates, and you should impulse yourself.
BUT, you will not be able to impulse yourself because FFA is 0 and your team is identical to your team. FFA makes impulsegrenade_self_impulse not count.

Oh yea, I've fixed it and also, added a code that kills the beam when the player touches the ground.

that plugin needs a lot of optimization...
