I read in an article that Cañas is using a new Wilson model which is not available in the market yet (you can see in the photos it doesn't have any decoration yet, it's all black). He said he changed because his model is not produced anymore. He also said that it's similar but a little more powerful than the old one. Wilson gave him 6 racquets to use ans will send him 8 more. Anyone has any information about this?
