Because the core is the backbone of the paddle, you must exercise extreme caution while selecting it. Any metal-based core will not assist your budget. You should choose a polymer-based or polypropylene core. The core is soft and flexible, so your shots will have just the proper amount of bounce. As a result, the paddle may generate that cushioning effect, and the paddle becomes less reflective. Aluminum core paddles are also available, although they are more costly.
