Greetings,
Having a cloaking device on an Imicus is definitely worth it. You can live quite well without it on an Imicus, but the cloak makes you more difficult to catch. Cloak is a powerful thing and it gives you options.
That is not safe place. Safe place is bookmark in the middle of space, where nobody can warp to you, unless they probe you down with combat probes.
You can warp between safe spots while scanning signatures and it will be very safe. You create more safe spots while warping.
The problematic parts are basicaly two:
the first is the site while hacking. People will decloak by you without any warning like probes etc. Cloak will not save you here (cloak on covops ship might do, but that would be another topic. Imicus is not a covops). First and most important task while hacking is to GTFO from enemy ships before they can gang you. Hacking is second.
Gates. If you jump into a camped gate, then you are likely history in an Imicus. But the cloak will give you better chance to escape. Cloak + MWD might save you. Go for “Improved cloaking device II” which doesn’t reduce your cloaked speed so much as prototype cloaking device.
I would recommend to practise more and later shift into an Astero. Astero is covops, uses “Covert Ops cloaking device II” and can warp while cloaked. Imicus can’t do that. Astero can deal with both above described situations very well… surprisingly well. Do not use the Astero fit which you lost. Combat Astero fit looks differently. Use ninja fit instead, more close to the Imicus fit. The Imicus fit which you have on zkill is fine.
Caveats -
Cloak-up as soon as you get to the safe-spot, giving your opposition no time to combat-scan you down in that location.
Launch your probes before you warp to the safe-spot, and hit Analyze immediately, so others can’t work-out your entry-point by scanning your clustered probes.
It’s worth defining more than one safe-spot, in case you carelessly manage to uncloak without realising.
When bored or just want to go afk for a long time but not in the mood to turn off EVE you can always use your cloaking device to harvest freighter loads of tears.
I love cloaks but they have their downsides. You can argue any T1 exploration frigate can get away with NOT using one. But it is safer and often more profitable to just have one.
