Ships & Modules

Sorry Peeps, I've seen the other Lev 4 Rattlesnakes fits posted in these threads but couldn't find a fit to my liking. My drones skills are maxed with access to T2 Sentries (no Heavies) and my missiles skills are 85% maxed with access to T2 Cruises. Would go with an active shield tank fit but since I'm planning to use these beasts for C3s in the future, I wanted to test out some passive shield tanking setups I've conjured up. Would like some constructive feedback on the efficiency of this passive Rattler fit for running lev 4 missions for SOE and Amarr. The Adaptive Invulnerability Field II would be removed of course for another shield amp when doing C3s, so no worries there. Also I'll be dual boxing 2 chars with the same skill sets and fits.

Hmm?? This fit is inferior to my fit by a pretty good margin. I see no reason to fly this over my fit.

Try giving better advice after you've sobered up please!

I detect some slight implications from this post saying that passive tanking the Rattlesnakes is no good for lev 4's. Is this truly the cast? If so, what fit do you recommend?

Also why refer to the Rapid Heavies over Cruises? I'm worried about falling asleep during the 35 sec missile reload times...

Well, the big thing with passive tanking is you give up a huge amount of DPS and damage application - which kind of defeats the purpose of the Rattlesnake. What I like about RHMLs is that you can load them with FoF missiles and they will take out anything within range. Damage application is also relatively decent so you don't need rigors, flares or any of the missile guidance systems. Here's what I like to include with my Rattlesnake fits.

5x Rapid Heavy Missile Launcher II, Inferno auto-targeting missiles
Drone Link Augmentor II
500MN Microwarpdrive
1-2 Omnidirectional Tracking Link II
Large Micro Jump Drive
3x Drone Damage Amplifier II
2x Ballistic Control Unit II (you almost get no benefit from a 3rd BCU with RHMLs)
2x Large Hydraulic Bay Thrusters II (more range, and faster missiles = less lost volleys)
1x Large Hyperspacial Velocity Optimizer II

The rest is basically personal preference, but there are a few options with the lows and mids.
