This is absolutely true, the Extreme was initially developed for Nadal, he decided at the eleventh hour to stay with Babolat, most likely because they came up with a longer contract. The Extreme was NOT developed for Ljubicic. He was signed on since HEAD had already done the R&D and wanted to bring the frame to market.2) Head has been thirsty for Nadal for years. YEARS. In fact the Extreme was originally developed for Nadal but he pulled out of the deal and decided to stick with Babolat.
