I recently bought 2 rackets at very good price from a local Hong Kong website.
One is NS7000 and the other one is Ti-10. At 26 lbs. stringing. NS7000 starts to vibrate whenever I hit while it does not occur in Ti-10.

Does anyone have the similar experience on high tensions ?
:o

Nope. No strange vibrations in my NS7000, I didn't string it over 25 lbs though. How sure are you that your racquet is genuine?

Nope, I am having the genuine NS7000 and NS8000, I strung my NS7000 at 28 Cross and 26Main. And I strung my NS8000 at 26+26... Basically, both rackets are very powerful. I particularly prefer NS8000 for smashing, otherwise... the 2 rackets are similar in most aspects to me...

Thanks.

One thing to take note though, is that NS7000 has a very special 'feature', its paintwork chips off very easily.... else most likely is a fake..

Thanks.

I buy from puppysports.com which many of my friends bought rackets from them. I am wondering if it is cause by the string job done by my coach and that I find the shape is a little bit change. I shall string again and see whether it works properly.

Tks.:rolleyes:

The shape is ISOMETRIC. I think it is OK. I also have that sort funny feeling when I first strung my racket....

Thanks.
