I'm not an expert on being able to find or even less measure advanced racket stats like swing weight, twist weight. I could probably find balance if I made a board for such things, but alas, all I've done is weigh it, which comes in at 320g (11.3oz).
As far as I can tell, there's 4 generations of Stings,
the originals with the crossbar in multiple headsizes
Then the SC, a midsize mold with no crossbar, I also own that, here it is. It's much heftier at 362g.
Then in the 90s there was the Sting Stretch Comp. Part of the High Beam series.
This last Sting Racket is from anywhere from 2003-2007 I believe. I've seen some NOS examples with Todd Martin on the marketing materials, looking old, as he did even when he was young. (he was 29 in that '99 USO final and looked about 37 but now I'm just getting sidetracked).
There seem to be two versions of the latest Sting, the Sting, and Sting Lite. The Lite lacks the Power slots, but is lighter, one can assume, by how much I have no idea. The regular Sting isn't that heavy to begin with. The rackets were not high end, they might have been sold in big box stores as a "nicer than aluminum two piece garbage sticks, but not high end material" option. All I can say is it hits nicely, and I dig the feel of the finish and the contoured under grip. I wish Wilson still sold that grip today. My rackets was deteriorating even though the racket was NOS, so I put a white Gamma grip over it.

Here's some highlights of me using this Sting recently. Serving was a breeze, I typically do well serving with larger head rackets. Like a lot of power oriented frames, it could sail on me when I really tried to swing through it, so I played more defensive, and lobs came naturally for some reason. Landed a number of deep ones. Occasionally the lobs were so good, my opponent here decided to call them out lol.
Keep your eye on the man in the white hat/dark blue shirt
