Here's a cool video that is featured on Tennis Warehouse on the new Wilson K-Factor racquet lineup. What's really neat about it is Roger Federer interviewing himself! It's really cool! On top of that, it features all the latest racquets in the Wilson K-Factor line up which are presently not available in the market yet. Check out the latest Wilson K-Factor video featuring Roger Federer in person. I personally liked Wilson's marketing of Roger Federer's winning shot against Fernando Gonzalez in the 2007 Australian Open finals with his now famous Wilson K Factor KSix-One Tour 90 racquet well as a great rally in which Federer won after some fantastic shot making against Gonzalez highlighting the "Kontrol" of Wilson's K-Factor technology. in this video. Wilson has defined 4 main key component's in their new K-Factor technology:

(K)arophite Black

-- A proprietary next generation structure created through a unique process at the nanoscopic level resulting in more feel and an even stronger and more stable racket.

(K)onnector

-- 2 external wings molded into each side of the hoop to increase dwell time of the ball on the string bed upon impact. This provides greater control and comfort with a larger sweet spot.

(K)ontour Yoke

-- New frame engineering technology that enhances stiffness at key stress points on the racket for improved torsionnal stability.

(K)ompact Center
