This would be the “optimal” fit I would use, but that’s with perfect fitting skills. (All 5)

Things I would downgrade to it’s “compact” meta-variant (if not alredy) from first to last.
Neut > Web > MWD > Scram > Adaptive Nano Membaren > Drone Damage Amplifier > Damage Control > Armor Repairer
So first switch the neut to meta, last the rep. And If all that isn’t enough just kick the neutralizer.
The only szenario this will give you an actuall advantage is when you fight an other Astero that uses a cap booster. So my train of thought here is the following:
If you encounter another Astero hacking a site, it is more unlikely to have a cap module fitted because it needs the midslot for data/relic analyzers. In that case, you should be able to outtank it no matter what. But if you are the one who is getting engaged, than the the neut can win you the fight.
If you fight anything else from T1 exploration frig or T2 covert ops, just keep the scram and web on it and your drones will make a quick kill.
The neut is really optional if you can determine what you engage.
This is of course my personal preferance and other pilots might disagree for good reasons with it.
I was btw wrong about the cap boosters, they seem to have all the same fitting needs.
Another thing you might want to pay attention when hunting in wormhole space are the different effects in them. (You can check them with sites like anoik.is). Once I didn’t manage to kill another Astero which was fit for speed because I underestimated the effect of the wormhole. It just outran me because I had fit a relic analyzer instead of a web at the time.
