Now a good test for those who claim that spin will slow down a shuttlecock how about trying this out: 1. Try to hit a deep clear with a new shuttlecock and note the distance. 2. Break two feathers of the same shuttle and do the same clear. You will note the obvious sharp drop in spin rate to the extent the shuttle now wobbles and has a tendency to drop prematurely to the floor. Take off a few more feathers and it will not fly at all. Now this loss in spin is not true spinning which many players, including coaches, wrongly believe. It is a lack of sufficient spin speed or rate that makes it wobble and fall.
