I was wondering about the two companies. I finally got a new Ti-10. I was playing with it today and I was very pleased by it's performance, but it's still hard to get use to it. My hits a little off, but in time I'll adapt to the Ti-10's heavy head. Anyway, I didn't get this racquet myself. It was bought from my friend. He went to Hong Kong during the Winter break and got himself a Nanospeed and me a Ti-10. I was trying to prove it's legimentcy. I already know the whole serial number reading, but one one thing, the serial number is covered by a sunrise sticker. The sticker is holographic gold color. It looks like a legit Sunrise sticker. On the sticker there is also a small black printing with "C1376990". I remember reading somewhere in the BC Equipement forums that Sunrise and PBSI helps confrim legititmency of a Yonex racquet, but we all know these stuff can be cloned. I dare not to take the sticker off just yet. I want to learn more about the Sunrise and Yonex relation. Is there anyway to confrim a sunrise sticker? And ultimitly confirming my Yonex Ti-10 Titanium Mesh Long 3ug5 is a real Yonex produced racquet without taking off the sticker? What harm is it taking off the sticker? I have already compared my Ti-10 with other real Ti-10s. I dont see anything different besides the head of the racquet. The paint on the very top head of the Isometric Head is a little more rough than other Ti-10. My friend told me that he bought the racquet at a trust worthy Badminton Store. If the history of the store is needed, I can question him more about it. The price for the Ti-10 was 110 USD with strings. If you guys want pictures of the racquet, just tell me the spots and I'll try to get clear pictures at the points.
