Here is some very intersting reading about Seven Dreamers shafts.
The company itself has been around since 1957, working in the development and manufacturing of composite materials. (Carbon fibre)
They are basically an aerospace company, but have developed their knowledge of carbon fibre for use in golf shafts.
They have several options for you to purchase a shaft.
The cheapest option is The Matrix series. This can be done by sending them details about your swing and completing a questionaire. They then give you 3 options on what shaft is best for you. Standard - Distance - Control. You then choose which option you want.
Another option is the Haute couture. For this option, you are required to attend a fitting session where they measure and analyse your “swing data” and “club head data”, then they design a unique golf shaft specifically tailored for you. Once again, the 3 shaft options are provided.
Here is more info from the TSG webiste. TSG Seven Dreamers thread (watch the video in the 2nd post)
Pics of one of the TSG'ers driver Modart Driver with Seven Dreamers shaft
Another TSG'ers thread about his Seven Dreamers shaft. S-Yrad with Seven Dreamers shaft This guy seems to be in Japan all the time getting fitted for different gear. Some of his threads are great reading.
I beleive with these two TSG'ers, they took the Matrix series option. This is 120,000 yen, which is about $1200.
Early thoughts from these guys is that the shaft does what it says.
Now I really want to go to Japan!!!
