I assume those are unstrung specs?
Interesting set-up. My own opinion is that it seems a little too headlight for something less than 340 grams. 5 or 6 pts tends to work better in that weight range since it puts more back into the head. A racquet 7 pts or more headlight with a lack of mass can lead to stability issues. More head heavy will also help on your serve if you can generate the same racket head speed.
Just my take. Good luck with it and let us know how it plays.
