MrMike, thanks for posting that video. I just bought the Ki5 PSE for a more arm-friendly racket and I thought my racquet was broken or something when I heard the "sandy" noise. It's fairly noticeable sitting in my quiet office, but I'm assuming it won't be a distraction while playing. The noise should only apply to the Kinetic line.
