There is no "swing weight" to swing on that board. Although your layer of 4oz will make it heavier, I am sure that the little bit of extra weight will be a positive. Too light to begin with. Made at the Cobra Facttory in Thailand..
You bring up a good point: weight. I'm curious, what do you consider normal weight for a shortboard, funboard, longboard (9')?
Send me your dinged, damaged, and yellowed.
It's all relative as they say. Depends on rider preference. A 9' board can be anything from super lite like Huck's Yater to a Volan glassed "old school board. Depends on what you like to ride. There is a wide range of preference.
what do YOU consider

"What do I consider Normal"?? Something between Huck's board and that Surfboards Hawaii in the other current thread.

well, the hits just keep on a comin', haha
The fin had a lot of those shatter type cracks, so I started sanding, to see if I could sand them out. I have sanded all the way to the wood, and guess what - again, no glass. Yep, even the fin was finished with resin, no glass. There IS glass in the halo, but sanding all the way to the wood, I never hit any glass. My plan is to sand it down to raw wood, then glass a few layers each side, with epoxy resin, sanded finish to match the board.
From this angle the core looks like a single piece of wood. If so, it's hard to imagine a 1/8th panel of wood can hold up without exterior reinforcement when used in that shape. I wonder if what we're looking at is not a single piece, but if we're actually looking at a veneer over ply or some other stiffer core?
You're sure there is glass in the "halo"??
I did repair on wood look boards from cobra, starboard windsurf seems to not have glass over but sandwich pvc in. Last surftech tufskin, with "cellulose sandwich core" are made with a thin, around 0,6 to 0,9 veenner, sandwiches between fiberglass and car paint over. Those boards have more flex, feel better on water (from riders) they are stronger to dings but they pressure dent and buckle easier than older pvc sandwich build. Except water intake problems, i find thin wood veenner sandwich build, aka timberflex well detailed to us by Greg Loehr here, well effective for surfboards.
What Cobra does for each customer like Surftech, BoardWorks and a bunch of Sailboard companies is "proprietary ". . The company submits their design and construction methods to Cobra. Cobra builds the boards to the customers specs that are often patented. Cobra signs an agreement to hold these design features and methods in the strictest of confidence. That is why most Sandwich type boards though they may be similar, no two companies build methods and materials are exactly alike. Most notable; Surftech and Boardworks. Similar construction techniques and materials, but not exactly the same. There are techniques and materials though that are know as "Public Knowedge" or Generic. Things like traditional methods; foam core And fiberglass skin etc. I'm assuming Cobra is still in operation. Haven't checked in awhile. For a Mass Production setup; They had scruples when it came to confidentially. Another company who had scruples and did a similar service, was or is KKL in Carlsbad.
