Here is a picture I came up with comparing the Yonex Plastic Shuttle and a regular feather shuttle (Victor Champion & Hiqua Red, both IBF approved). The plastic bird drops so quickly at the end comparing with the feather's smooth fly. During the regular drive, I notice that even for a horizontal drive, the plastic bird will fly faster than normal feather ones and drops faster than normal ones. I was using the plastic bird today....and lost the match in 20 minutes just because I can't even hit the shuttle!! (5-15 & 3-15) 10 points were I just hitting the air or frame, 8 points for hitting the plastic bird way too long and 6 points were couldn't tell if it's going to be in or not when receiving service (and they were all in; all of them were sudden drop-downs at the end) So, after the game I started to wonder why can't I even touch the shuttle? even time I hit it , it would be right a the frame.....so I took a look at my freinds game (they borrowed the plastic shuttle from us), and draw the picture based on their game. Even if both types of birds are hitting the same spot, their flights are totally different. Conclusion: Plastic sucks!! I'll have to remember to bring feathers with me next time! I will NEVER use the plastic again!!
