I'm thinking of switching sticks to the PDR. I have it strung with SilverString 1.25 - my favorite - at 55 lbs. I added my normal rubber band dampner, but it still pings like crazy and the sound is driving me insane. I've tried a few other "normal" dampners and it pings too. What's up with that? With a rubber band on SilverString on any other racquet I've used there was never any ping at all. Anyone have any ideas for me? Is it just the racquet??
