The holders of the Silver Goblets, James Cracknell and Matthew Pinsent, will be challenged by the Croatians Nicksa and Sinisa Skelin, who beat them in the world cup three weeks ago, at Henley (2-6 July).
Both crews are also on the starting line of the second world cup round in Munich today. Also in the Henley line-up are the South Africans Ramon Di Clemente and Donovan Cech who pushed the British pair hard in last year's Goblets final.
Henley has attracted 494 entries with plenty of talent in the club events to compensate for generally poor interest in the opens. The Grand for international eights is a straight final between the US and Canada. The GB squad try out their new eight this weekend in Munich, with Ed Coode back after injury.
