Guys, I bought a MP 55 3 weeks ago. The price was very cheap 70$ CA whitout string. I string the racquet at 23lbs. The racquet seem to be too head heavy. Even with that charachteristic I Couldnt deliver big smashes . The grip seemed to be too big and I couldnt feel the bird. I also have another racquet : blacknight 2008 . It's very very very light (79g)but very powerful compared to MP 55. It is also string at 23 I heard that with heavy racquet you have more power but it seems that it's the opposit for me. Could it be that im more a arm player or something. I tought by buying the mp 55 I would increase my smash litterally but im very disapointed.
