I'm interested in trying out this racket but I cannot find enough info on this racket. I'm not even quite sure what the specs for this racket are. If anyone can give me some racket specs and maybe a few reviews, I'd much appreciate it. Thanks!

It's kind of a low class/end Nano Speed. From this pic from the 2007 catelog, the frame is only carbon graphite. The shaft is HMG and Fullerene. Doesn't seem too special to me.

It's also medium stiff, head light, and only available in 3U in the US. Here's the link from Badminton Alley, though they're specs don't seem very accurate, compared to the catelog.

i actually got it few weeks ago as my warranty replacement of MP 66.
First day of using it i pulled my previously pulled my shoulder msucles again during smash. Power is quite good, and control is good but lacking compared to 66. then on the other hand it might be because it's using BG 80 which i think is too bouncy. (at least for me)

edit: the paint seems to be quite weak because i was walking and accidently tapped it on the soccer net and has chip across 11 and 3 o clock positions.
