Tecnifibre - X-One Tennis Balls

Absolutely incredible tennis balls. Superior in every aspect. The longevity of these balls is unsurpassed, they last longer than any penn or Wilson balls. The quality is exceptional. Balls are perfect, no imperfections like pro penns. They use top of the line Bridgestone rubber, which really makes a difference. One note they seem to be medium duty felt, so not nearly as heavy as US Wilson opens. The balls do fly and have exceptional speed because they are slightly lighter. Probably closest ball is the Babolat trophy balls but these are much better. They are more expensive but worth it. Not popular here in North America, where recreational players are not willing to pay extra for tennis balls, but they are very popular in Europe. They are voted the best ball by players and coaches not sponsored by the big money. Try them and you will not be disappointed, only drawback is you will not want to play with any other ball afterwards.
