Hi everyone, my wise 2086 just arrived yesterday and when i first strung on it, i noticed a slight clicking sound as it maintains tension during constant pull. I will like to ask if it is normal. http://youtu.be/ywSU0nsMxqk It's not really audible in the video, but basically there's a slight clicking sound. I'm just wondering if there's anything wrong with it. Hope someone from badminton central can comment on this. Thanks!
