Here is a question that many ask:
“My mom got these tennis rackets a year or two ago. They’ve always looked old, and of course they haven’t gotten any better. I have a hard time hitting the ball with them because they seem hard and brittle. Do the strings need to be replaced? Would it be cheaper just to get a different racket. We don’t play for more than just fun, and we got these rackets because they were cheap. So I guess it doesn’t even matter that our rackets are bad. But I just wanted to know if they need replacing.”
Got any suggestions?

There are other strings out there, but these mentioned are the pick for mine. I would get two reels of string if I was just starting out. A cheap nylon from say Prince (Tournament Nylon) and a poly from Luxilon (Big Banger original) or even one of the cheaper poly’s mentioned. Stringing yourself will enhance your interest in the game and show your kids how committed you are to their sport. It is also a bit of fun when you get the hang of it. It is not hard, but it pays to be patient in the beginning.
