Racquet terminology

Picking out a new racquet for yourself or a loved one can be daunting. With 20 different brands and hundreds of different models, choosing the right racquet can make one's head spin. Kind of like what happens to me when I walk into a perfume store or cereal aisle. At Tennis Warehouse, I think sometimes, we forget not everyone is as into tennis as we are. Our everyday tennis vernacular isn't very everyday and common to most recreational players. So I want to break down racquet terminology in layman's terms in hopes of clarifying what makes racquets play and perform the way they do so you can make a more informed decision before buying your next racquet. (From Tennis Warehouse I hope.)
