Energy pulse vs Energy stream weapons

[Cylapse]

For style sake, I love stream weapons.... just the thought of an intense fusion beam cutting its way thru **** *heh* Pulse weapons are cool though, and I was hoping I would be able to mod a set of Pulse Cannons that doubled as extremely weak PDS, but doesnt seem possible *winks* Ah well.

I say stream... but then again I dont recall what the pulse research area gives you.. Any enlightenment?
