Nice to see that you're more "focused" on picking on supposed errors in other peoples posts instead of the topic itself since I notice you didn't comment on anything else in my post.

Its pretty much known that the 2-letter codes are just distribution codes. The manufacturing of the top-end racquets are mostly all done at the YY factory in Japan, unless that has changed in recent times. Manufacturing info is clearly printed either on the end-cap or the shaft.
So how would Yonex churn out marginally differing specs or finishes for lots destined for different codes? I don't know. In terms of process optimization, it does not make much sense. If this (difference in finish) is true, does it have to do with higher QC or ISO requirements for products destined for Japan as opposed to say, Philippines or Malaysia? If there is truth in the claim that there are different finishes for different codes, then we should observe that difference uniformly in say all SP coded products as opposed to all JP coded products. Otherwise, I would put it down to "systemic anomaly"

Only Yonex knows...

I am not sure about SP vs JP, but I have a TW and a US NS9900, both are 3U. I can tell from my personal experience that the US one feels heavier and stiffer than the TW. I don't know why. Others at my club also think the same when they hold the rackets.
The difference could be well just the weight range of 3U (85-89g). The paint job looks the same to me.

I have owned 3 original Arc Z-Slash with 3 different codes (SP, TH and JP) and the difference I can tell is only based on the finishing/painting quality. I noticed that my TH coded was the lowest quality with the font spacing of the "Z-SLASH" emblem written on the 7 o'clock was not even. It looked like a "Z-SL ASH" instead. I have noticed that flaw when I bought the racket but the other piece left on the shop was even worse with some other flaws.
The SP coded was better but still some flaws can be spotted under granny's style of inspection. When I looked at the racket from the cone straight to the frame, I noticed the wordings written on the shaft were slightly shifted (not geometrically straight on a line) and it has a couple of sharp-edge grommets on the frame.
The JP coded so far has no finishing/paint job flaw under my naked eyes inspection... or maybe not yet !
Too bad I did not take any picture of those two TH and SP coded before I sold them but I personally believe that the JP coded has passed a higher standard of QC.
In terms of material quality, weight, balance and durability, they are all pretty much the same and should be within the range of manufacturing tolerance.

well..looking at the uneven cross sections of racquets.. its definitely possible that there is even variation within a series itself.. and how yonex may do some selection. I would if i were them...
