I got this Ti-10 in China and it has this PBSI logo on it. What does this mean? Is this a real Ti-10?
Yes it is. It means that it has been approved by PBSI ;-) It meets the standard quality set for world class player in Indonesia PBSI : Persatuan Bulutangkis Seluruh Indonesia means : Association of Badminton in Indonesia
I believe that the PBSI logo also comes with the additionals letters "SP" after the model name since I have the Ti SP SA SP.
I don't think that is correct. Singapore is too small a market. The total number of SP racquets sold in Hong Kong alone bearing the HK suffix in the cone serial no. will outnumber those sold in Singapore. SP racquets are officially marketed all over Asia except Japan and China.
search and read the previous discussed treadsssss, woven SP = south pacific hey this tread is very old too
