Usually, international players use 3U rackets. In this case, I'm rather sure as the Bs12 is very quick anyway and has a somewhat low BP compared to most Pros' preference. 4U would just be too light and lack power.

I'm going to guess and say that it is either an X-Feel Blast or a Satelite 6.5 Blast. My reasoning is that there are some splashes of red on his racquet and these are the only two on their website that have it.
My guess would be that the Indonesion Super League is right around the time where many players start using their new materials if they got a new contract....usually, only the apparel is affected by league play (i.e. players wearing the team sponsor's jersey rather than their usual brand) and rackets aren't. Would be a mess if players had to change rackets all the time Is it just me or does Boonsak's racket look Voltric-y? Can't make out any details though... Oh, and I agree with olli on Hu Yun's racket. Looks like a Sat 6.5 Power to me (don't see any red, and he used the 'Power' rackets before as well).
Is Taufik using the Arcsaber 11 because from a photo from the Malaysia Open it looks like he's still using the Arc10 ... .....
He was still using the Arc 10 Premium during the Djarum Superliga...He'll probably switch to the Arc 11 at the All England.
