The simple answer could be that rackets are made in batches based on country. If they are all coded this makes sense. However, I wonder whether there is an element of those countries who order the most get theirs first?
Why Brunei was chosen for the green MX90's is anyones guess.
As i get to know Victor i may understand more about the processes behind the manufacture and time delays. However, it does suggest to me that too much information is leaked too early before the manufacturing begins. That said, it could be there are only small tester batches released initially. These find their way onto the forum and we all think they are in mass production when in fact there hasn't been a decision to release onto the market.
This sampling system is not uncommon because if a racket doesn't play well then why have several thousand made and sat in a warehouse? So, by heavily sampling, this provides greater indicaters regarding potential demand. Then, when orders are placed from each country, the rackets are made to order.
So, I've been interested in the JJS since there have been many good reviews on it, namely Paul's and informally kwun's, and also because I've had great experiences over the past 2 yrs with my MX80/70 and RKEP XP60/70 which are based on the MX and BS frames which are both powerful and fast.
With the upcoming soon to be released MX90 rated 4/5 stiff and HH by Victor, many including myself, have been left wondering if it is the same model as JJS that has been repainted. Well, I've done some scouring around and can tell you that kwun is right... it will be a different beast... with emphasis on beast, as it'll have stiffness in between MX80 and MX70!
I'm also enjoying the 3UG5 MX80 (my second tier racket after the 3UG5 Z-Force). I was very close to purchasing the MX-JJS, but realised that all the relatively "high powered" reviewers either mentioned the MX80 was also a really good racket, or have not been able to comment on it much (ie. Paul Stewart). I think as long as you are relatively fit (and young hehe) and are at an "Advanced" level, the MX80 is just as good, if not better than the MX-JJS. Just speculation on my part of course.
