I don't know what lay-up or mods Tsonga has... But the APDC is a perfect foundation for customization. Tsonga must have been tinkering and practicing with this stick for the past year or so to make the switch final. Wondering why wilson was using him to promote the cobra... Maybe they had a heads up that he was in talks with babolat. Whatever the cost, hope he plays well this year.. he's a very exciting player to watch.
