It is a 95, it was sold as a 98 for marketing reasons.
This erroneous rumor about Head measuring the Head size using only the inside of the frame just won't die; if you do the math - as others have done on these boards - it jus' don' add up!
I'm not talking about either of those well documented things.
String pattern AND spacing between the strings themselves (and spacing between the outside strings and to the hoop) has to be taken into account.
The actual measurable HOOP size is only part of the story. (Novak's racquets play a lot closer to a PS97 than to a Six.One 95)
Then again, I imagine many people think the old Bab 2010 and 2013 APDs actually play like typical 100 sq inch racquets and that the PA 100 models are exactly the same as the old APDs because their hoop sizes are the same.
