The Dunlop 500 tour is a terrific racquet, I like the extra pop I get on my serve. The 500 tour plays well in all phases of the game.
Good demo, the racquet just wasn't for me. Very maneuverable but a lot if miss hits due to the oval shape of the face. Racquet was marked with type of string but kit the tension and size. As for the demo program, you can't beat $7 to try before you buy; plus the ease of using the demo and returning.
