I've talked much about how playing a smaller size head like the Fed racquet is much better than the oversize racquets. I've been wrong. It's true that the 90 inch Fed is like an extension of your brain/arm, but only if you are a top pro. I was in a brutal match, and I loved the 90 in normal play, but when you are REALLY BOOKING IT, that little, tiny difference makes a huge difference, running over for example to get a backhand that's way deep, the racquet just isn't there in nano-second time. With a K95, even though you aren't there totally, you at least can still get it back into play. If I'm just hitting with someone good, I prefer the 90, it's just so accurate, but in real play 95, and remember I am going against what I have always said, its better. The 95 has the accuracy, plough-through, of the 90, with the spin potential and forgiveness of a Bab or Head 100. So yea I am learning things, strings and racquets are SUPER IMPORTANT for advanced players.
