It is a nice racquet, I actually got to hit with it recently. Absolutely sick amount of spin, but it was also a little too powerful and hard to control for me. The specs listed on the handle are -
weight - (304 grams) 10.7 oz (unstrung)
balance - 6 points headlight
string pattern - as you mentioned, 16x15
head size - 99 in^2
It did not state the flex
How did you get to the earth? what are you supposed to be doing here? How are you leaving?
