For a general exploration Stratios fit refer to this post (there are other good fits in the thread as well):

As for your Astero fit, if you're using it for PvP/Hunting you don't need the probe launcher or the gravity capacitor rig or the Omnidirectional (in fact you shouldn't fit this to the Astero in general).

You'd go for something like this (I don't have a fitting tool with the updated ships right now so I'm not sure if this fits):

[Astero, New Setup 1]
Drone Damage Amplifier II
200mm Reinforced Steel Plates II
Damage Control II
Small Ancillary Armor Repairer, Nanite Repair Paste

Warp Scrambler II
Limited 1MN Microwarpdrive I
Stasis Webifier II
1MN Afterburner II

Covert Ops Cloaking Device II
Core Probe Launcher II

Small Polycarbon Engine Housing I
Small Anti-Explosive Pump I
Small Nanobot Accelerator I

Hobgoblin II x5
Warrior II x5
Hornet EC-300 x5

Dual prop + scram web for range control, ideally you'd want to take on targets that can't hit the edge of scram range well. Honestly though, using the Astero as a hunter isn't a good idea cause even though you get the element of surprise, you don't have the dps or tank to take on most threats.

Well give us an idea of what you're trying do with them.

Dato, thanks for the link and fits. I'll rethink what I've come up with.

Everyone else, I'm regularly flying in hisec and lowsec with corp guys who have Ishtars, doing escalations and such. Occasionally dropping into a wormhole to do exploration. My aim with the stratios was to have a good all around PVE boat for such occasions.

The astero fit, is just theory at work. I'm no good at pvp.

The fit's are quite fine for a beginning and worth of testing out. Just fit the ships, fly out and test for yourself.

However, here are some suggestions:
If possible, fit T2 Probe launchers, and if you cannot fit T2 Probe Launchers, just fit cheap T1 Probe launchers.
Furthermore, for solo-PvP, rather consider working with T2 Heavies as 25 mbit/s drones, and not sentries, and make good use of webifiers. Maybe even consider using two webifiers.

The ships seem a bit fragile. I guess you focus on choosing your targets wisely and focus on finishing your targets quickly and disappear again.
Play those ships like as if they were "ninjas", sneaky, striking out of darkness, quickly, and ruthless.

Just like a shark. :D
