My broken Wilson N4, the racket broke suddenly halfway during my game when i was doing a backcourt clear:crying: , I've clashed the racket before, but the place where it broke is definitely not the place where it clashed. I've only strung it at 23Lbs. The N4 have been my favorite racket with good maneuverbility and ability to product decent smashes. But it's durability is turning me away . My 10 years old Cab25 is much stronger than this after going through much tougher clashes.
