This is my personal feeling for this racket.
my main racket is Nanoray 900, my second racket is an arc 11.
I quite agree with the point made by jasonyjw (page 13).
I'm using BG66 UM 26 Lbs there all my rackets.
this racket is really Even Balance, compared to nr800 (slightly in handle), and arc11 (slightly in head)
if I comparte the NR900, nr800, Arc11
Stifness: NR900> Nr800> Arc11
(NR900 is clearly more rigid than the Nr800)
Defense: NR900 Nr800 => Arc11
(2 Nanoray are easy to move)
Drives: NR900> Nr800> Arc 11
(I do not know how to explain it, but on the drive, shuttle out like a ball racquet gently and quickly slowed at the end of the race, the shuttle does not come out !!)
Smashes: Nr800> Arc11> NR900
(This is the point Faigle compared to other rackets I use, I can send very lours smash with my N800, but because of the rigitidé I feel that my smash are fast moin with NR900, but it must be that I can play well, to get used to the racket)
Comfortablility Level: Nr800> NR900> Arc11
Forgivness: Arc 11> Nr800> Nr 900
(With 900 Nr: you shoulds hit from downtown to-have a decent shot, and NR800 ARc 11 are a little more forgiving, so if you are late on your shot and you dont hit in center,it can be hard time with NR 900)
This is just my personal opinion.
