Say I am a club player trying out a new tube of shuttles and everyone agrees that they are too fast. How can we slow the shuttles down to make it playable? 1) Internationals will tip maybe 4 feathers at their ends.Shuttle is not damaged. 2) Oldies will insert the handle into the rim and twist the handle so as to widen the diameter of the rings. 3) Some will just fluff up the feathers with a swipe of the racquet. 4) Now I heard that it is possible to hold each shuttle thumb out and 3 fingers inside the shuttle and twist the junction of the feathers and the stem with those 4 fingers. Does method 4 work and is the shuttle playable after that? Do pros know sth we don't know and are able to perform 4) undetected? Just your experience will be much appreciated.
