Some great test footage:

Observations:
1) The ship keeps warning of overheating. Though the warning is that the engines are too hot, IIUC the entire ship uses the same heat budget and it is the peculiar weapons aboard that are making this overheat. After every couple seconds firing there is a warning, so obviously this is not good. So here's my usual pitch--install ballistics. Twin Revenants and twin Mantis will do
much more damage, and do it from the first hit instead of killing shields first. Weapons that overheat after every few seconds are not good weapons, and
erkul has the stock weapons doing far less damage than ballistics, which travel further, faster, so will hit more often. Running hot weapons makes it difficult to switch back and forth into stealth, so get some ballistics.
2) The stock reactor is EM noisier and less powerful than the Eclipse. Upgrading the reactor is going to make this much easier for energy management and make it stealthier at the same time. The Eclipse will give you about 1/3 increase in power while reducing your EM signature to 1/3 of the stock Cirrus. This is a no brainer.
3) The coolers are the same, which is probably ALWAYS a bad idea for a stealth ship. Install low EM sig primary (Nightfall has 1/3 better cooling with 2/3 the EM signature over the installed) for stealth ops and a huge oversized secondary cooler (left off in stealth) for dumping IR fast when you need to. The Snowpack dumps heat more than 3X faster than the installed. When you switch it on it will dump excess heat at a fantastic rate so you can evade IR detection (including missile locks).
***These two changes (reactors and coolers) reduce both EM and IR signatures greatly, and anyone planning to use the stealth in this ship should plan these changes. You can't improve your radar cross section, but most times players and NPCs are not actively pinging to catch sight of each other, since this unzips your fly. So do not ignore this ship's greatest advantage--it is a stealth ship--and optimize this.
4) No rotation nor lateral acceleration (strafe) rates posted yet, but this does seem to rotate faster than the Vanguard.
5) Keep in mind that though this is a medum ship with mostly medium components, it was nerfed with a small radar. If as per the norm EM and IR sensors scale with radar, this ship is pretty blind compared to other medium ships. That should change how you fly it. Though you can presume somewhat that others can't see you, you need to keep in mind what you can't see too. This issue is tied with the missile issue as to why you might prefer the Hoplite. Two Hoplites bring more shield, hull, firepower, and speed to the battlefield and three will bring much more.
6) There is a lot of disinformation out there of late about the new Sukoran shields, but they appear to be what they were supposed to be, stated several months ago--they are bigger with faster refresh than any other medium shields. This was supposed to be accompanied by a required directionality, and that was the job of the second seat (which apparently has no function in this iteration). Point is, until you know better; leave the shields!
