A friend of mine just bought Astrox 22. It's a 70 grams racket. He's an intermediate-advanced player. Before, he uses a 3U BS12. I've borrowed the racket for a quick match, seems okay. Feels fast and I can deliver decent smashes/clear even though I had timing issues. Perhaps need more time to be fully comfortable. I asked him what he thinks about that racket. He said it feels noticeably easier on the elbow/shoulder and he feels it's really fast. When I play against him, I don't really see a decrease in his smashing/clearing/drive power. I feel he's slightly faster than usual in his reaction. Although, he did miss some easy shots. Perhaps because of the same timing issues I had. I'm thinking of buying the same racket if it really is easier on the elbow/shoulder while delivering a good performance. Have you guys tried a really light racket? What has been your experience?
