That is my fit up there so I'll answer for it.
The double nano fit is intended more for efficiency and defense against Asteros. Aside from smartbombing Proteii and stealth bombers, an alert pilot can bail against any other type of threat, including interdictors. The simple reason is speed: 3.3km/sec cold, 4.8km/sec heated, which is faster than an Astero or an interdictor. With Alpha skills the ship aligns in 4 seconds, 3 seconds with better skills - remarkably good for this job. The scan pinpointing array is choice here because any other choice of array will be stacking penalized too hard against the double gravity capacitor rigs and the pinpointing array allows for more precision in scanning. Scan strength can only go up with skills with this fit.
The Medium Shield Extender fit is prefered by some times, in part by me. It will tank a smartbombing Proteii long enough to bail or a single smartbombing battleship on an outgate (3000 alpha from 8 large faction smartbombs for reference). Personally I'm a bit of a fan of having an Expanded launcher on hand.
For alphas I recommend the Probe, like this:
Code: Select all
[Probe, Probe - No Tank MWD No Guns Alpha Explorer Meta4]
Type-D Restrained Nanofiber Structure

Type-D Restrained Overdrive Injector
5MN Quad LiF Restrained Microwarpdrive

Warrior I x3
Acolyte I x3
Cheap as chips, under a mil. With Alpha skills, aligns in 4 seconds, 3.4km/sec cold, 4.9km/sec heated. Alphas can't use pinpointing arrays, so the extra mid on a Heron isn't very useful. You may T2 the lows if you prefer.
Having killed someone before who was using overdrives on his Probe I can say that hunting one of those with an interdictor can be rough: a standard cloaky dictor has a roughly 8 or 9 second recalibration time, by which a good pilot will be gone. (He almost got away. My last bubble did the trick: he probably burnt out his MWD, I believe I almost burnt out mine.) Asteros likewise are pretty slow under a MWD, barely workable with a shield nano fit (which nobody smart uses for w-space ambushes) so you've got a pretty good chance of slipping away. Figure the Astero pilot has Cloaking to IV, which most people do, that means a 6 second recalibration time plus a ... 4 second lock time. At that time you should be already outside point range going at least 4km/sec -- you're gone.
