I was reading the latest issue of Tennis Mag and the editors choice was the Wilson N5 98. The article is as follows: "Today's racquets are made of billions of woven graphite fibers that have a microscopic spaces between them. In the n5, Wilson fills these gaps with silicone oxide crystals, claiming this process increase the frame's stability and power as well as ensuring that the racquet will play better, longer. We will need more time to evaluate the last assertion - IT TAKES UP TO TWO YEARS BEFORE THE FIBERS IN A TYPICAL RACQUET GO "SOFT", CAUSING A LOSS OF CONTROL AND POWER". I have never heard of a racquet going soft, if true, I think the manufacturers should put expirations dates on the frames. Also the N5 looks just like the Traid, probably same mold.
