Weeks before one of my friend bought a tube of RSL Classic Tourney for our game. The shuttles are really durable, and the feel of hitting is also nice. So I went to buy another tube (actually from other shop) for our game today. Unfortunately, although still durable, but not as good as previous tube. Also, the shuttles gave me a very strange feeling, seems that they were not stable enough. When I looked at the two tubes, I found that the caps are different. Also, the green color of the wrapping paper is slightly sharper than the other one. So is that one of the tubes is fake? Or just because it comes from older batch, or from other batch which supposed to be distributed to other areas?
