I played with it past 2 days. The grip it comes with is SO fat. I took it off and placed a flatter one. after you put the overgrip on you can't feel the large buttcap as much.
Once the grip size was fixed and I put some lead on 3 and 9, it was the similar balance to my ag100...
to be honest... I can't feel an extreme difference with the extra 3 inches of head. It doesn't feel more or less forgiving.. I have to brush up more now because of the string pattern. I definitely miss the unintended super spin that would come off my racquet from the ag100.
