I have been told by a friend who's now playing in Europe that the guys in his club treats the shuttles prior to using. Basically, a new tube of shuttles are all dipped into water (just the feathers) but not soak. And they are inserted back into the tube and left for about 24 hrs. Then they are taken out to dry (but not under the sun, just leave them to dry in the room) before using. Apparently, this makes the shuttle more durable. Is this true ?
