A single gimballed C3 beam stays on almost fully with 4 pips in weapons, takes shields down quite quickly, then I also have the gimballed C3 cannon for hull of the bigger stuff. But it really isn't needed on anything Asp or below, it's too expensive to shoot and miss when the beam chews them to bits for free - Clippers and Pythons don't even get the first layer of my A5 shield down, running with just a single booster cell (think it's a B0, can't run the A. not enough juice) - plus I like the comforts of fuel scoop and cocking computer

With a little bit of module tweaking I'm running 15.68 theoretical power required from the 15.60 plant. Turned the cargo hatch off, I don't have any cargo hold anyway, and the FSD/scoop/life support all set to priority 5 - if I need life support my weapons are going away anyway, and I'm running away!
Took down an Elite NPC Anaconda with accompanying sidewinders in an assassination mission with a little bit of discretionary running away to get some shields back, but I still had 80% hull left when he went pop

Love it. The Viper doesn't even come close.
Unfortunately the A4 power plant simply can't run all the things I'd like for my little tank

so I make do with compromise frame shift jump (fuel scoop makes that largely irrelevant anyway) but I have decent thrusters.
Interesting how the layouts differ. I just want to blast stuff in RES and war zones, and my setup suits my flying "style"

I only have to run away when I'm trigger happy and get a "wanted" tag.
