One of my favorite PvE combos use to work like this.
Tyken's Rift 3 (back when it would drain 70+ energy)
Torpedo spread 1 from fore, photon launcher
HYT2 from rear plasma torpedo launcher.
If done properly and done right I could destroy 3 frigates before the rift closed.
With a lot of science skills nerfed I now I use something more like this.
I've yet to find a new way to take out a frig group in one pass with a science ship but i can not take out a single ship faster with a new build that looks like this.
