I am offered a coaching sponsorship from Wilson. The problem is that I currently play with Babolat APD. If I'd take the deal I'd need to start playing with Wilson rackets. With this deal I'd get a bowl of overgrips, lot of clothing and bowl of grips for free. I wonder if Babolat could give me a counter-offer. If I take this coaching sponsorship, does it mean that I have to compete with Wilson rackets or do I only have to coach with Wilson rackets. Does anyone know?
