I mean, I cannot prove to you via video that I have hit with a pro. http://www.thewestboroclub.com/meet-our-staff/ Is the club I belong too, that page shows the bio's of the tennis staff at our club. Just read through them and you will see which pro I am talking about. Check his ATP page if you would like. I agree that when he hits with us, even if we tell him to go all out, it is probably hard for him to really take it serious. He definitely hits harder, he definitely has more control and he does everything better. He does net a ball occasionally though during a rally. Just saying. The best money I have ever spent was joining a 10 week clinic with my buddies with him running the clinic. For 300 bucks I was able to get more tennis knowledge and plenty of advise on things I need to work on. Money well spent.
