At least two pieces I have checked. I own 2011 model and it has steel weight in the handle located at 4-11cm from butt. You can check it by magnet or visually in the middle wall inside handle. I have also checked 2009 in our tennis shop and it has steel at 0-7cm . So it looks that 2009 is more polarized. Can anyone confirm if his racquet has about same steel weight locations or it is only in this one case?
