Andy Triggs Hodge: The GB rower was one of the surprise changes after moving from the pairs to the men's four.
Great Britain's rowing team have changed an incredible 10 of the 14 Olympic class crews from last year's World Championships.
Only the men's single scull, women's double sculls, women's pair and men's lightweight double sculls remain the same as last year's showpiece in Slovenia, where Britain topped the medal table.
The biggest surprise sees Pete Reed and Andy Triggs Hodge - who have raced as a pair for the last three years - moved to the men's four.
Alex Gregory and either Tom James or Alex Partridge will complete the team once they have finished testing.
World Champions in 2011, Ric Egington and Matthew Langridge, have moved from the four to a strengthened eight that will be stroked by 20-year-old Constantine Louloudis.
Greg Searle is also in the eight and now on the verge of completing a remarkable Olympic comeback, 20 years after winning gold at the 1992 Games in Barcelona.
