KKK has not been in top form since the 2010 WC. Since then, his form has dropped and they lost their attacking style somehow....either they can't be bothered (which would be incredibly stupid&lazy) or they can not sustain the high pace like they used to. I don't think TBH is very dependant on him, he played with Hoon Tien How(?) in the Thomas Cup (I think) and played pretty well, winning at least one match against a top pair. Recently, KKK has been the weakness as he plays too many overconfident or defensive shot. For me, LYD and CY are pretty much at the same level right now. On the really big occasion (WC, OG), there are very few pairs who stand a chance against the Chinese, as they're always in top shape for those events, and usually CY is just a tiny bit better at the net in those matches than LYD, winning the attack more often for FHF, who also has a better smash than JJS. Other than the Koreans, only the Danes are dangerous - Boe is also once of the best net players out there, and even if he has severe weaknesses when compared to the others, his serve-return game is superb, winning the attack very often. He is not as quick and CY/LYD, and has a much weaker defense, but at the net, he's on the same level, I think. Although I really hate his on-court attitude and delay tactics -.-"
