Anyone heard before N7 shuttlecocks? my school is going to have a tournament and yet N7 shuttlecocks will be for the tournament.. my gosh!
i think he's talking about the new generation of plastic shuttlecock. http://www.mizuno.jp/badminton/shuttle/
If you're referring to the shuttle that CHOcobo linked to above and if they're anything like what they're supposed to be like I wouldn't have any worries. I'd imagine I've played with worse shuttles in some of the small local tournaments and club matches. Overall, I would imagine that the quality of your play with have a much greater effect on the result of the tournament than the type of shuttles you play with. I've just Googled N7 shuttles and is it these that you're playing with? If it is, whilst I doubt they'll be near Yonex F-90 quality but at least they're feathers. No matter what shuttles you're playing with, I'd just relax, enjoy it and try to play my best if I was in your situation. Letting little things bother you can just make things harder for yourself so it's probably best not to think about the shuttles you're using too much.
