Not sure about Asian countries. But at least in Canada, All the high end LiNing shuttles are too fast.... ***and YES, I purchased the correct speed for the Canadian Summer Season and have tried multiple batches from the 2013 Summer and 2014 Summer seasons...*** i have tried the A+100, A+300 and A+600 Ultimate... Unfortunately, all 3 of these shuttles are too fast. But the 300 and 600 has good cork feel as well as on the better side of durability. The A+300 is probably the fastest of all. To compensate, I have to buy the slower speed of what I should be buying for other brands of shuttles. OR if during a game, I would have to kill every other tip on the feathers to slow it down, but kills the durability of the shuttles as well... For now, Aeroplane Black, Yonex New Official, Official, AS50/40 are some of the ones I have tried and the speed of these shuttles via their speed ratings are very similar. anyone else having issues with LiNing shuttles being too fast?
