You'll won't find many (if any) top professional athletes who have benefited from NLP or use NLP on a regular basis. For a while I thought Pete Sampras used NLP, but then realized he was saying "TLP"; I don't know what that is. I guess people who are REALLY talented would just be bogged down with the mechanizations that NLP fiddles with. But NLP is great for unexcellent people.  It sounds like NLP could help your tennis game quite a bit. Unfortunately I don't know enough about NLP to give you any strategies or whatnot. Good Luck. Sam
