(Continuation ofa pm converstation between Spacefueladdict and Hieronymos)
..Sorry, but I've never worked with the X3 Editor, being technically deficient, and don't know how to view specs like ship speed, yaw/pitch/roll, acceleration, shields, etc.
As you've no doubt seen, I use a more archaic method for reworking ship specs.

Ship Description: “Rumored to be reverse engineered from an alien derelict found nearly a thousand years ago, the powerful Terran Imperator M2 Class Star Destroyer is a unique hybrid with an identity crisis that cannot decide if she is Carrier or Cruiser. By far the most heavily shielded warship in the Terran fleet, she carries armoring second only to the Valhalla Cruiser, but has the speed of the lighter Tyr class Cruiser. Her heavy laser armament is consistent with that of a Terran M1--in other words equal to a Split Python M2! She also carries 28 fighters internally. Intended primarily for use as a clandestine base for Terran Naval Intelligence operations in Commonwealth territory, the Imperator has an enormous cargo bay for extended cruises, and can mount many Commonwealth heavy weapon varieties and missles. This makes her the most tactically flexible major combat vessel in the Terran fleet, and makes her able to resupply herself in enemy territory during wartime. Her only drawback--as a carrier--is her small fighter bay. As a cruiser, her turrets are small by Terran standards, and her weapons generators closer in size to those of a carrier. Additionally, the Imperator is extremely expensive, which will ensure that she is never used widely by the Terran military."
COMMENTS: ISD as M2. M2/M1 Hybrid.
For nerfing Springblossom, I would personally first look at the other 3 Terran/ATF M6's specs..and bring Springy's specs closer to the averages or means they reflect, while hopefully still preserving Springy's identity as the premier high-speed "boom-and-zoom" corvette. Her remarkable speed is what really sets her apart from all other M6's; and makes her virtually invulnerable to attack by almost anything--when well piloted.
Her speed at 360m/s (with steering of 6.0 to boot) is almost 300% of Katana's (at 136m/s), and Vali and Vidar are even slower. Compared to Commonwealth M6's the fastest Dragon variant has 172m/s.
Preferred Option I would consider for reinventing Springy:
M6/M3+ Hybrid "Light" Corvette: preserving much of her 'swiftness'--but sacrificing offensive power or shielding, plus cargo. Thus, something like
reduce hull from 45k to 37.5k;
shields reduced to 400Mj;
3,250 Mw Shield Gen'r (Katana's);
reducing her back turret to 1x from 4x (can still mount SSC to toast any M5 or M4 capable of tailing her);
reducing laser recharge from 570 to 465;
reducing her cargo from 2k to 1.3k (Katana's; note that the ATF M6's are 850 & 950);
price up 25% to MCr. 7.574
Comment: with above specs she's still almost twice as fast as next closest M6's, and with laser recharge of 465 she's got virtually unlimited juice as long as she switches to MAML when power drops. Her weak hull makes her vulnerable to fast MD-armed M4's, and her speed still allows her to break contact with everything except M5's an a few M4's.
Maybe this tweak is too hard on her..whatcha' reckon SFA?
