Are you looking for the badminton racquet that best suits you? Then don't look at what your friend is using! Just because someone else is kicking butt on the court with his racquet doesn't meant that same racquet will give you those same skills. However, unless you built exactly the same way he is, and unless you in exactly the same physical condition he is, you're not going to get the same results if you use the same racquet he is. Instead, why don't you invest a little time finding the badminton racquet that works best for you?
That guy out there might have more strength in his wrists or his arms than you do so he's able to lift a heavier racquet. And that heavier racquet is giving him even more power. Or he may not be as strong as you so he's using a lighter racquet with and isometric head so he doesn't have to be as careful where he hits the shuttle. The best badminton racquet for YOU is the one that gives YOU the best results.
That means you'll need to do a little research, and try out a few different racquets. You might even have to buy a few before you find the best badminton racquet for you. You should always try to buy a used racquet when you can, that way you can save money until you discover that magic racquet that works just so for you. I recommend this idea to all my friends, and I'm recommending it to you too.
Sure, the pros use fancy racquets - nothing like the ones in the badminton set you bought for your backyard cookout. They're much more durable and they're built for speed, power and control. They're build to handle the stress of competition. However, regardless of who is using what racquet, that doesn't change the fact that it might not work the same way for you. if you want to find the very best option in badminton racquets for you, then you'll need to do a little leg work. But, you can rest assured that you won't be sorry!
