the most prestigious really depends, for team, it'd be Thomas/Uber Cup. for individuals, i'd say World Individual Championships. but above all, Olympics
A grand slam in badminton must include the mother of all badminton tournaments which began before all the other badminton tournaments started, the All England. Started in 1899 the All England was once considered the unofficial World Championship. A grand slam that doesn't include the All England is ridiculous.
Razif/Jalani wow! today only i know they won 4 world championship. Wow i think i wasnt born yet when the sidek brothers in action. In the time of park joo bong and li yong bo. Wah !!!!!!
i don't think 4 World Champs, cos that'd be 8 years, a helluva long time. if you read the earlier posts, you'll understand the results are for World Grand Prix Finals, not World Champs
