I recently traded in a Volkl DNX 3 for a Babolat Aeroblast and decided to play with a good friends racquet. I immediately fell in love with it, sold the babolat, and bought this racquet. This racquet is worth the price. I wouldn't go with the k1 because it is too powerful and not enough control. Definitely the best. – Brett, Orange, CT, USA
