Yes, maybe around that time-frame, I am not good with the dates, but I do see a pattern in the WCM usage. It is as though IR thought what he was doing was silly and cut down on using bits-and-pieces of WCM techniques and tried to do more holistic treatment - one good example would be enna solli pAduvatho - from en mana vaanil (2002). BTW, There are folks here who really know WCM. But I am the one who probably talks more (knowing little) - a arai kudam :-) .
