The balance was not head light enough for me, and I'd like it to be heavier with that additional weight at the handle.It can get pushed around, as I had torsional stability issues with off-center shots. It just needed more mass. I would change out the stock grip or keep it wrapped with an overgrip because it gets slick fast. I also might add a bit of plow through and stability on serves and volleys by adding weight to the hoop and handle.
I liked the spin and manoeuvrability. It has a nice feel, with great access to spin from all areas of the court. I also liked serving with this racquet. It proved to me that I can play with Spin Effect technology without changing my stroke mechanics. It plays fast and lively.
