Does using a faster version of a shuttlecock in training benefit you when switching back to a slower speed? I don't clearly understand the factors that affect shuttlecock speed so excuse me here.
Green, blue, red, slow, medium fast, fast. You go up according to the weather I'm pretty sure. I'm talking about plastics so yeah. I play with green. I don't think so :0, just use the shuttlecock speed you use in tournaments or in your casual games.
