I just want to know is it really hard to choose a shuttlecock cause i usually dont try to shop and just buy the yonex one. for me these are the only choices you have to pick -plastic or feather is there really any other factors to choosing shuttlecocks?
Yes. You need to choose the correct speed for where you're playing and the correct shuttle for your price point. You could go, for example for Yonex AS-10 or you could go for F-90. AS-10 is a relatively cheap, relatively low end shuttle and F-90 is the Yonex tournament shuttle and very expensive. Read Dinkalot's shuttle review for more information.
