Hi all, I will have a badminton tournment next month and only feather shuttle will be used. When I played with my friends, we only used those yellow plastic shuttles. My question is, 1.) what is the main difference between the 2 in terms of gameplay? is the feather shuttle heavier? do I need to use a bit more power just to get the same effect as hitting a yellow plastic shuttle? 2.) Feather shuttle does not last long. We are given 1 new feather shuttle for each set (21 points). As more and more feathers come off as the game progresses, do I need to adjust my swing (hitting power)?
